CraftSha Rivet and Snap Fastener Tools This is a set of tools with a striking base. These are tools used for leathercraft. There are minor scratches from use, but there are no problems with usage. I am selling these because I no longer need them. Please refrain from purchasing if you are concerned about minor imperfections due to home storage.
