These all natural stone drink coasters are made from 100% natural stone in the USA. Some made from marble and some made from granite.
These coasters are all hand made by us here at Pgh Marble Stones.
Our coasters are sold in many different colors of marble or granite.
Unlike other marble coasters that are 3.5 inches square or round. Ours are a true 4″, this makes it much easier to sit a common glass or coffee mug on. As like all natural stones, every coaster is unique and will not look like the next. With stone being naturally heavy, these coasters will not stick to the bottom of your glass. They come in 4″ round or 4″ square. They are all cork backed and are sold in sets of 4 or 6.
