5/16 x 12 inch Cork Board Squares made from natural cork. Suitable for coasters, cork tiles, wall tiles and cork backings. Cork Squares can also function as wall coverings, bulletin boards, coasters and hot plate mats. 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 tile is 5/16" x 12" x 12". Each box contains 6 square tiles. Cork Squares are eco-friendly as no trees are cut down in the production of cork. Bulk available.
