Use these all the time
"I have a full set of these that I use all the time with silver clay. I recently started using polymer clay as well and used two from my set (the 2 and 2.5) with the metal clay. I was happy to be able to purchase a duplicate of just those two so that I was not using the same hole punch with both types of clay to avoid cross contamination. I am able to clean any clay stuck in the end with a long copper rod that is thin enough to reach all the way through the tool and pop the excess out. One of the metal tips came out one time (I think my granddaughter was using it to make a hole in polymer clay and pressed with all her might). All it took was a little super glue to get to firmly back in the plastic handle. These are really great!"
