Quick answer
The FUN CUP Size A is a great starting point if you have a light flow and are new to menstrual cups. Its 20 ml volume and medical silicone make it comfortable for lighter days.
Why size matters for first-time cup users
Menstrual cups come in different sizes based on flow volume and cervical height. Choosing a size that matches your actual needs makes insertion and removal easier, especially when you are still learning the technique.
The FUN CUP Size A holds 20 ml, which is on the smaller side. That is ideal for lighter days or for someone who wants a lower profile cup to start with. If your flow is heavy, a larger capacity cup might be a better fit.
Material and comfort considerations
Medical silicone is the standard for menstrual cups because it is body-safe, flexible, and hypoallergenic. The FUN CUP Size A uses this material, so you do not have to worry about irritation or odors.
The trade-off is that silicone cups can be slightly firmer than TPE alternatives. If you have a sensitive bladder or cervix, you might feel the rim. Many beginners find that a softer cup is more comfortable, but the FUN CUP's firmness helps it pop open easily.
Decision rules for choosing the FUN CUP Size A
- Flow volume: If your heaviest day requires changing a pad or tampon every 4-6 hours, the 20 ml capacity is sufficient. For heavier flows, consider a larger cup.
- Cervical height: The FUN CUP Size A is a standard-length cup. If you have a low cervix, you might need to trim the stem. If you have a high cervix, the cup may sit deeper and be harder to reach. Measure your cervical height during your period to confirm fit.
- Experience level: This cup is beginner-friendly because it is small and easy to fold. The firm rim helps it open reliably, which reduces the frustration of a cup that does not seal.
