These replacement game pieces are printed at 600dpi, single 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 stretch. 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 and stack better than the originals.
