Our eco-friendly coasters are sleek with a subtle artistic touch made out of certified organic bamboo fibers and cornstarch. It makes even a regular cup of room temperature water look photo-ready when used. Place them for a modern statement on any tabletop. Bamboo is a fast-growing, renewable resource. Our bamboo coasters are 100% biodegradable and free of melamine and plastic, making it an environmentally conscious choice to be kind to yourself, your family, and our planet. *Slight color variations are a natural by-product of the bamboo fiber.
