Square Coasters, Pottery, and Specialty Shapes have different lead times. If your order contains a combination of these products they will be shipped together when the order is fully complete. If you would like your items to be shipped separately based on their different lead times, we suggest placing separate orders for Square Coasters, Pottery, and Specialty Shapes. Crackle glass pottery is food safe for dry foods. Not dishwasher or microwave safe.
