Beeswax is an incredibly effective tool for storing food. Bee's Wrap makes wraps in all different sizes that you can use for all sorts of things: to wrap sandwiches, as a cover for open cans, cheese, butter, and even one large enough for a loaf of bread. The bee's wax makes this fabric semi-adhesive, so when you fold it onto itself, the heat from your hands creates a seal. These are a lot more effective and less wasteful than tin foil or plastic, and they are reusable as long as you wash them between uses. They're a lot more sustainable in the long term, too.
