WHAT IS COCORO? We’re introducing a new way of going through your period. Cocoro knickers are made of thin fabric, are washable and reusable. They are like all other knickers except for an added detail: Cocoro knickers also absorb vaginal fluid and menstruation. They’re designed to be used the same as pads, on their own or combined with other products such as tampons or the menstrual cup. Day, night, winter, summer, every day or only sometimes…use them any way you want, whenever you want.
