PIXISS Ceramic Tile/Coasters are perfect for creating coasters with alcohol inks, markers, acrylic paint, resin, and more! Our tiles are specifically designed for arts & crafts. Unlike traditional tiles found in home improvement stores, our tiles are smooth on all sides, which means no grooved bottoms or notched sides. PIXISS Tile/Coasters are non-glazed and may need sealing before applying alcohol inks. In addition, the set comes with perfectly sized peel and stick cork pads to protect the bottom side of the coaster.
