A twin pack of Naked by Unicorn period cups which fold flat, into their own case. A waste-free alternative to traditional disposable towels and tampons. Made of 100% medical grade silicone and the sterilising/carry case is made of food grade silicone. Each Unicorn cup can be used for anything up to 12 hours, holding as much as 4-6 times that of pads or tampons. Unicorn cup can be sterilised at the end of each cycle (boiling water or sterilising tablet). Can be used repeatedly for up to 10 years. The cup is inserted into the vaginal canal and opens up inside to create an air-tight seal, it sits below your cervix to collect blood flow. Comes in 2 sizes, the twin pack offers users the opportunity to find the right fit, or use both, depending on lighter or heavier flow days. QR code on the packaging directs users to an instruction video, how to insert, remove and sterilise.
