3/8 x 4 inch Square Cork Coasters made from natural cork. Suitable for coasters, cork tiles, wall tiles and cork backings. Square Cork Coasters can also function as wall coverings, note boards, coasters and small plant holders. The corks come with no adhesive, but can be glued with many household glues or construction adhesive (like Liquid Nails or Gorilla Glue). Cork is a natural thermal insulator. Cork's natural properties resist mold and mildew and are hypo-alergenic. Each cork coaster square is 3/8" x 4" x 4". Each box contains 6 square tiles. Cork Squares are eco-friendly as no trees are cut down in the production of cork. Bulk available.
