Our solid cherry wood coasters, which provide a beautiful rich red color, are four inches in diameter making them large enough for most cup or glass bases. With your investment in mind, we use a marine grade sealant on all sides to protect them from water damage to help ensure they have a long life. We add a final touch by applying cork to the bottom of each coaster to prevent them from scuffing or sliding on surfaces. As with all of our products, we draw all our own art to create unique designs for our customers. If you do not see something you like, we would love to work with you on a custom order.
