Hand painted in acrylics and sealed with a satin sealer. Also, If the color choice you see isn't listed, please just let me know in Notes to Seller. Your choice of size. Large is just about 2"; Medium is 1 3/4" and small is 1 1/2". There is a pre-drilled hole on the underside to make attaching them easier, too. Flat machine screws are recommended for install. They are not included but are easy to find in any home store. (many people have ordered for a decorative addition to a jar lid and don't want the screws, and that is why I don't include them) My mom has an assortment of these - in varying colors - in her Norwegian-themed kitchen and they make a wonderful display!
