Holbein Canvas Stretcher Pliers No. 10 Holbein Canvas Tacks No. 100S This is a set. Both are new and unused. I purchased these a while ago and have kept them in storage without using them. I looked it up, and it seems that the same canvas tacks are no longer sold, and the No. 100SK appears to be the successor. The outer boxes have some damage, but the items themselves are unopened. They are in good condition.
