This adorable set of 4 coasters is made of 100% cotton. Each resembles a green apple with it's favorite "bug friend" attached to a leaf. They are delightful to look at, while protecting your furniture from water rings. And they will give your surroundings an added touch of home made warmth. A single coaster is 4'' in diameter. Care: hand wash in warm water, lay flat to dry. Ironing will help to stiffen them up. All of my items come from smoke and pet free environment. Feel free to contact me with any questions
