Plastic-free plates that were made to party. Preserve's Compostable Plates are made with the power of plants, returning to the soil when you're done using them–instead of sitting in our landfills for centuries. These 7" plates are freezer, microwave, and oven safe up to 420F, and can be thrown in your backyard or municipal compost at the end of life. Manufactured in the USA from renewable resources, you can now be a little more sustainable when you need to go single-use!
