Sirona’s Menstrual Cup is the most modern, nature-friendly, economical, and leak-free way of experiencing complete period comfort. It is a reusable, silicone cup that collects your menstrual flow rather than absorbing it. and is worn internally, like a tampon. It is ideal for those who care for their own health (cups don’t disrupt your natural pH) & the environment (disposal of sanitary products creates toxic waste). Cups are made of high-quality medical-grade silicone that is widely applied in products such as infant nipples, catheters, etc (it is toxin-free, odorless & hypoallergenic).
