Natural cork top tiles are hand produced from the first harvest of cork oak trees. Harvesting the cork does not harm the tree and the cork bark regrows, it is a truly sustainable product. This unique covering is designed for terrariums but has many applications including wall and ceiling coverings adding warmth and texture to a room. The texture easily hides seams lines between tiles allowing for multiple tiles to be placed together. Dimensions: 12x12 inches varying thickness between 2.5-5 centimeters. We would love to hear about innovative and unique uses for this product.
