3/8 x 12 inch Cork Squares are made from natural cork. Suitable for coasters, cork tiles, wall tiles and cork backings. The corks come with no adhesive, but can be glued with many household glues or construction adhesive (like Liquid Nails or Gorilla Glue). Cork Squares can also function as wall coverings, bulletin boards, coasters and hot plate mats. Cork is a natural thermal insulator. Cork's natural properties resist mold and mildew and are hypo-alergenic. Each cork tile is 3/8" x 12" x 12". Each pack contains 6 square tiles. Cork Squares are eco-friendly as no trees are cut down in the production of cork. Bulk available.
