Pomé menstrual cup is an eco-friendly alternative to tampons and napkins which cannot be recycled. Pomé cup is reusable up to 5-10 years depending on usage. It is made from medical grade silicone to ensure it is safe. Instead of absorbing menstrual fluid, it catches it. When worn properly, user will not feel anything at all and can do her daily activities as if she has no period. The cup sizes are based from the average cervix sizes of women. Standard size is perfect for beginners or women with light menstrual flow. Box includes a reusable liner.
