The perfect pair for the bemused guest, these coasters are ideal for a casual drinks event. They're also excellent for holding candles or just as a cute display piece. Made with a smooth finish, the coasters can hold glasses of most sizes. By Shax products are handmade per order and will look slightly different to the product images. Pieces may also have small air bubbles, which is a result of the hand poured working process of jesmonite and is a natural, authentic finish. While By Shax products are water-resistant, they should not be washed (by hand or dishwasher). You can wipe the surface of the product using a damp cloth and this should get rid of most stains if done immediately.
