This original handcrafted Bamboo Gear Coaster Set of 4 is our original Graphic Spaces design. Our high-quality wooden gears are laser cut in 1/4" bamboo wood making them thick and dimensional. Each one measures 3-7/8" in diameter. We spray a base sealer and clear top coat on each piece making them resistant to moisture and very durable. This set of 4 gear coasters come beautifully packaged in a clear gift box ready for gifting.
