This package contains 1 set of four coasters that we have constructed from sections of giant sequoia trunks that have been culled from our nursery stock. The beautiful bark remains intact on the trunk of each ½ inch coaster. The top and bottom of each coaster is coated with an oil based preservative to bring out the wood grain and protection from liquids. The handcrafted wooden base holder is 4x4 inches square and created from sanded and treated locally grown black oak wood. Felt is mounted to bottom of the base to protect a table.
