These durable marble coasters make a perfect gift for any fan of Philly or maps. Made by The Painted Lily, a one-woman business in the Philadelphia region, each tile has a protective clear coat on the front and a thin layer of cork on the back, to protect furniture.
 
Each piece measures 4 inches square and 3/8 inches thick. Please expect very small chips and irregularities along the stone's cut edges, as it is part of the handmade process.
