Learn how to pick the right Fun Factory menstrual cup size for your body, with practical advice on fit, comfort, and care for first-time users.
Quick answer
Choose Fun Factory FUN CUP Size A if you have a lighter flow or a lower cervix; choose Size B for a heavier flow or a higher cervix. The Explore Kit lets you try both sizes.
Why size matters for comfort and leak protection
A menstrual cup that’s too small may leak or be hard to reach, while one that’s too large can feel uncomfortable or press on the bladder. Fun Factory’s two sizes let you match the cup to your anatomy and flow—not the other way around.
Both sizes are made from soft, medical-grade silicone that adapts to your body, so the main difference is capacity and length. The right size should sit below the cervix without shifting, and you should barely feel it once inserted.
Silicone quality and care ease
Fun Factory uses soft, flexible silicone that is gentle on sensitive skin and easy to clean. You can rinse it with mild, fragrance-free soap and boil it occasionally to keep it hygienic. This material is also free of latex, BPA, and phthalates.
Decision rules for choosing your first Fun Factory cup
- Size A (smaller, shorter): Best for lighter flow days, lower cervix, or first-time users who want a smaller cup. Holds less fluid but is often easier to insert and remove for beginners. If you’re unsure, start with Size A unless you have a heavy flow.
- Size B (larger, longer): Designed for heavier flow, a higher cervix, or users who have given birth vaginally. Holds more fluid, so you can go longer between emptying. Choose Size B if you regularly need a super tampon or have a high cervix.
- Explore Kit: Includes both Size A and Size B in one package. Lets you try both sizes to see which fits best without committing to one. Ideal if you’re between sizes or want to test fit before deciding.
