This is a real Aspen wood coaster, 3.5-4” in diameter and 0.4” in depth. The wood is sanded and smooth. The design is made on Adobe illustrator and then engraved into the wood to give it depth and texture. The design reads, "Yellowstone National Park". Check out my full collection of national park coasters! Locals love these coasters which are locally sourced and created by a small business owner. These coasters make great gifts and are popular year-round.
