These are very multi-purpose! Presumably they are to be used as water resistant bags to carry soiled diapers. However, we use them for all sorts of things; bathing suits, lunches, snacks, etc. - you name it.

Water resistant and colorful, they close with a drawstring and toggle. Wash these bags in lukewarm water and either hang to dry or dry on air in the dryer. No fabric softeners, chlorine bleach or other whitening agents.
100% nylon.
