If you’re comparing my mimi vs Hello Disc, you’re likely looking for a reusable menstrual disc that feels comfortable, stays in place and suits your body.
Both options are popular reusable menstrual discs. Both are suction-free, made from medical-grade silicone, designed to collect menstrual flow rather than absorb it, and can be worn for up to 12 hours.
But there are some important differences when it comes to sizing, fit, firmness, capacity, removal style, beginner friendliness and sustainability credentials.
Here’s how they compare.

Award-Winning Sustainable Period Care
A key difference between the two brands is recognition.
my mimi has been awarded Best Sustainable Period Care Solution in Australia in both 2025 and 2026 by the Australian Health & Wellness Awards.
This recognition reflects my mimi’s focus on reusable period care, sustainable alternatives to disposable pads and tampons, and thoughtful product design that supports comfort, convenience and long-term use.
A single reusable menstrual disc can replace hundreds of disposable period products over its lifespan, helping reduce waste while also saving money over time.
For customers looking for a reusable period product from an Australian-designed brand with independent award recognition, this is a strong point of difference for my mimi.
1. Two Sizes vs One Size
One of the biggest differences between my mimi and Hello Disc is sizing.
my mimi comes in two sizes: Small and Large.
This gives you more flexibility when choosing a menstrual disc that suits your anatomy, flow and comfort preferences.
The my mimi Small is 61 mm in diameter and holds up to 32 mL. It may suit:
- beginners
- people under 30
- those who have not given birth vaginally
- people with a lower cervix
- light to moderate flows
- anyone wanting a smaller, softer-feeling fit
The my mimi Large is 68 mm in diameter and holds up to 61 mL. It may suit:
- heavier flows
- people over 30
- those who have given birth vaginally
- higher cervix positions
- users wanting maximum capacity
Hello Disc uses a one-size-fits-most design with a 68 mm diameter and 50 mL capacity.
A one-size disc may work well for many people, but it does not offer the same flexibility as choosing between a smaller or larger diameter.
When it comes to menstrual discs, fit matters. A disc that is too small may not stay tucked securely, while a disc that is too large may feel uncomfortable. Having two size options can make it easier to find the right fit for your body.
2. Lower Cervix Compatibility
Hello Disc has a 68 mm diameter, which is the same diameter as the my mimi Large.
For some users, this larger size may feel comfortable and secure. However, for people with a lower cervix, narrower anatomy or sensitivity to larger menstrual discs, a 68 mm one-size disc may feel less suitable.
This is where the my mimi Small offers an important point of difference.
At 61 mm, the my mimi Small gives users a smaller option that may feel more comfortable for lower cervix positions or for those who find larger discs too noticeable.
Having a smaller size available can also make the learning curve easier for people who are new to menstrual discs.
3. Beginner Friendly Design
Trying a menstrual disc for the first time can feel intimidating, especially if you are switching from pads or tampons.
my mimi is designed with beginners in mind.
The soft silicone body makes the disc comfortable to fold and insert, while the integrated loop tab helps make removal easier. This is especially helpful for first-time users who may feel nervous about reaching and removing a disc.
The two-size range also helps beginners choose a more suitable starting point rather than being limited to one larger diameter.
Hello Disc also includes a removal tab and is known for its adaptable double-loop design. The tab can be worn in different ways, including dropped, tucked, flipped or trimmed.
This flexibility can be useful for experienced users who want to customise their removal style. However, some beginners may prefer the simplicity of a single soft loop tab that is ready to use without trimming or adjustment.
For first-time disc users, my mimi’s combination of soft silicone, size choice and simple loop tab makes it a strong beginner-friendly option.
4. Comfort and Fit
Every body is different.
Your cervix height, pelvic anatomy, flow, age, birth history and personal preference can all influence which menstrual disc feels best.
This is why my mimi’s two-size range is such an important feature.
The Small offers a more compact 61 mm diameter, while the Large offers a wider 68 mm diameter with higher capacity. This makes it easier to choose a disc that better suits your body instead of relying on one standard size.
Hello Disc is 68 mm, which may be ideal for some users. But because it only comes in one size, there is less flexibility if you find that larger diameter uncomfortable.
A better-fitting disc can help improve comfort, reduce movement and support more reliable wear.
5. Firmness and Support
Firmness is one of the most important differences between menstrual discs.
A very soft disc can feel comfortable, but some users may find it harder to insert or keep securely positioned. A firmer rim can help the disc tuck behind the pubic bone and stay in place during movement.
Hello Disc is often described as having a slightly firmer feel. Some users may like this extra structure, especially during insertion.
my mimi is designed with a soft disc body and a supportive double-edge rim. This gives the disc flexibility while still providing structure.
This balance is especially useful for:
- active lifestyles
- gym workouts
- sport
- walking or running
- swimming
- long days out
- overnight wear
The supportive rim helps the disc stay positioned while the soft body supports comfort.
If you want a disc that feels soft but still has supportive structure, my mimi offers a considered balance between comfort and security.
6. Capacity and Heavy Flow Support
Capacity is another key difference.
my mimi Small holds up to 32 mL, while my mimi Large holds up to 61 mL.
Hello Disc holds up to 50 mL.
For light to moderate flows, the my mimi Small may be enough. For heavier days, overnight use or longer wear, the my mimi Large offers a higher capacity than Hello Disc.
This makes my mimi particularly flexible because users can choose between a smaller, beginner-friendly size or a larger, higher-capacity size depending on their needs.
7. Active Lifestyle Use
A menstrual disc should fit into your life, not interrupt it.
Whether you are working, exercising, travelling, swimming, sleeping or running errands, you want your disc to stay comfortable and secure.
my mimi’s soft body and supportive double-edge rim are designed to help the disc remain tucked behind the pubic bone during everyday movement. This can be especially helpful for people who are active or who want extra confidence during sport and exercise.
Hello Disc may also work well for active users, depending on individual fit. However, my mimi’s two-size options and supportive rim design give users more choice when finding a secure fit.
8. Removal: Single Loop vs Double Loop
Both my mimi and Hello Disc include removal aids.
my mimi has an integrated soft loop tab designed to make removal easier and more controlled. This can be especially useful for beginners or anyone who has struggled with discs that do not have a tab.
Hello Disc has a patented double-loop tab that can be worn in several ways. It can be left dropped, tucked, flipped or trimmed depending on the user’s preference and cervix height.
This adaptability is one of Hello Disc’s most recognised features.
However, not everyone wants to adjust or trim a removal tab. Some users may prefer a simple, soft, integrated loop that is ready to use from the start.
If you want maximum tab customisation, Hello Disc may appeal to you. If you want a straightforward, beginner-friendly loop tab with no trimming required, my mimi may be the simpler choice.
9. Sustainability
Both reusable menstrual discs can help reduce reliance on disposable pads and tampons.
my mimi is reusable for up to five years with proper care. That means one disc can replace hundreds of single-use period products over time.
This is one of the reasons my mimi has been recognised as Best Sustainable Period Care Solution in Australia by the Australian Health & Wellness Awards in both 2025 and 2026.
For customers who want a reusable period product that supports a lower-waste lifestyle, my mimi offers a strong sustainability story backed by award recognition.
10. Designed and Based in Australia
my mimi is proudly designed and based in Australia.
The brand focuses on creating reusable period products for Australian customers, with sizing, comfort and education at the centre of the product experience.
Hello Period is a New Zealand-based brand and Hello Disc was co-designed with menstrual cup expert Kim Rosas.
For Australian shoppers comparing reusable menstrual disc options, both products are well-known. However, my mimi stands out for its Australian design focus, two-size range, award recognition and beginner-friendly fit options.
Which Is Better: my mimi or Hello Disc?
The better menstrual disc depends on your body and preferences.
You may prefer Hello Disc if you:
- are comfortable with a 68 mm one-size disc
- want a highly adjustable removal tab
- like the idea of wearing the tab in different ways
- prefer a slightly firmer disc feel
- already know that a 68 mm diameter suits your body
You may prefer my mimi if you:
- want two size options
- are new to menstrual discs
- want a soft, beginner-friendly disc
- want a more personalised fit
- want a smaller 61 mm option or larger 68 mm option
- have a heavier flow and want up to 61 mL capacity
- want a supportive double-edge rim for active lifestyles
- want an integrated soft loop tab for easier removal
- prefer an Australian-designed brand
- value sustainability award recognition
Final Verdict
Both my mimi and Hello Disc offer reusable menstrual discs designed to make periods more comfortable, convenient and sustainable.
Hello Disc is well known for its patented double-loop tab and one-size 68 mm design. For users who know they are comfortable with a larger disc and want tab customisation, it may be a suitable option.
However, my mimi offers several key advantages.
With two sizes, a soft beginner-friendly body, supportive double-edge rim, integrated loop tab, high-capacity Large option and recognition as Best Sustainable Period Care Solution in Australia in both 2025 and 2026, my mimi is a strong choice for anyone wanting a more personalised menstrual disc experience.
If you are new to menstrual discs, have a lower cervix, have struggled with one-size products before, or simply want more flexibility when choosing the right fit, my mimi may be the better option.
