One Luna cup will last you for years. It is made from 100% soft medical grade silicone which means it holds three times as much as a tampon, making it great for a heavy flow and night-time use as well as lighter days. As the Luna cup has no string, it can be used when swimming, exercising and travelling, always making it discreet. It is environmentally friendly and an economical alternative to tampons and sanitary towels as it generates less waste. It collects rather than absorbs your menstrual fluid, meaning it won’t disturb your vagina’s delicate pH.
