I got a $13 cost with tax totaled and free shipping on a multi-leather punch set made from over seas. It has a nice cloth case with tiny 1/8 inch to 3/4 inch round punches. Total 12 punches. I know they won't really be good on metal, but gaskets is what I would be using them for, like intake and crankcase gaskets.
