Beppy gives you freedom! The Beppy Sponge is a super soft and squishy. string-less menstrual sponge. It is worn internally and inserted into the vagina like a tampon. where it absorbs menstrual fluids. Because Beppy Sponges are flexible. they adapt to your anatomy and are comfortable to wear. They can be worn during sport. swimming. while sleeping and during sex. as it can't be felt by you or your partner.
