Black & White Ceramic Coasters (4) - Debby OlsenThese Ceramic Coasters are ready to go. They have been hand painted using an acrylic pour method using black and white acrylic paints. After 2 coats of resin they are smooth, shiny and protected. Coasters take two months to make due to the curing process. They usually sell fairly quickly. This set of 4 are all different, and original. They make a great gift, just tie them up with a bow and add a gift tag. Just note they can be used with hot and cold
