Mooncup Size B is the original reusable menstrual cup made from medical-grade silicone, designed for those under 30 and/or who haven’t given birth vaginally. Soft, comfortable and worn lower than a tampon, it offers confident protection without dryness or irritation—one cup, no fuss.

Providing up to 8 hours’ wear, Size B holds up to 28.8 ml—around three regular tampons—and can last up to 10 years, saving money and up to 2,500 disposables. The smooth silicone and trimmable stem help you find a personalised, secure fit for movement, sleep, swim and travel.

Fold to insert, position low in the vagina and, when ready, pinch the base to release the seal and remove. Empty, rinse or wipe and reinsert; always follow the usage guide and empty every 4–8 hours according to flow.
