These glue squeegees are made from a polyethylene blend that epoxy simply cannot adhere to. That means they're easily reusable, and will maintain a clean edge. They can be easily trimmed to size or shaped with a scissors to make filleting tools, and can be serrated with pinking shears for uniform spreading of epoxy over large areas. Includes two large (5-7/8'' x 3-7/16'') and two small (3-3/4'' x 2-7/8'') squeegees.
