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.
