The perfect pair to hold your trinkets or serve as elegant coasters for your coffee table. Made with a smooth marble finish, the trays can hold glasses of all sizes, and come with a cork backing to protect your surfaces. 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.
