These replacement game pieces are printed at 600dpi, double sided, laminated plastic, that are cut completely through for easy removal. They still require a sharp hobby knife and a pair of scisors because the lamination will streach. Snapping forward and backward on a single game piece from a strip works well also. These are water proof, and very durable. They are thicker and heavier than usual (.067in) and are easy to pick up.
