Tampax Cup is co-designed with a female OB-GYN to fit more women more comfortably. The SoftCurve™ shape provides a snug, soft fit that reduces pressure on your bladder so you get up to 12 hours of Comfort-Fit protection for your period. Tampax Menstrual Cup is made of 100% medical grade silicone and is 0% dyes, perfume, BPA or latex. Between cycles, menstrual cups can collect dust and germs. So we made a durable case that protects your cup and keeps it clean when not in use. And, it’s compact enough to take it with you wherever you go.
