Steam sterilization bag
The sterilization bag is included with each menstrual cup as it also serves as a shipping container.
Do not throw away the product packaging bag after unpacking, you can use it to sterilize the cup before/after menstruation.
Pour a few tablespoons of water into the bag, put the cup inside, too. Seal the zipper and put it in the microwave for a few minutes for maximum power. Steam sterilization is one of the most effective and more than 99% of bacteria will be destroyed.
The instruction of use is on the back of the product and is also part of the LUNACUP menstrual cup user manual.
