The Wysi wipe is the multi purpose miracle that should live in your diaper bag or purse. It is about the size of a cert and expands once you add water. It is about the size of a traditional paper towel once expanded. It is biodegradable and reusable. The Wysi wipes are made of 100% cellulose without any added ingredients. All you need is a splash of water. Different liquid - different use. Resealable, waterproof bags have a ziplock top to keep Wysi® clean and dry until you need a fresh cloth.
