High Density Urethane (12 pieces)

Used to force sheet metals into impression dies. Trim these pieces of 80 durometer urethane a bit smaller than the impression you are working with. Safer and cleaner than using lead as a backing material.
(Twelve pieces 1/4 inch thick x 1 inch square)

We recommend these end cutting pliers to cut urethane or leather into the desired size and shape.
