If you are looking for ways to reduce your use of plastics, here is a great product!  They are reusable, breathable, plastic free and compostable.  The fabric is 100% cotton.  The coating is a mixture of organic beeswax, organic olive oil and grapefruit seed extract.  The wraps are easy to care for - just wash in cold water with mild soap.  Do not use them to wrap hot food, or to cover a bowl that contains hot food - allow all foods to cool prior to wrapping.  Each wrap lasts a year or more.  Colors and fabric patterns vary.
