Material: Jesmonite Dimensions: 10 cm in diameter, 1 cm thick This item was handmade and polished in our studio. Each piece is unique, so the ordered item may be slightly different from the one in the photo. Small holes and imperfections are due to the natural solidification process of the product, therefore they are inevitable characteristics that make each object unique and artisanal. Ideal for use as coasters. They are sold in pairs (so two coasters) and the price is for the pair, not for a single one. Each item has a thin layer of cork at the base to protect furniture/tables.
