Good brass punches at a good price. The build quality wasn't the best on several of the sets that were sent to me, but that didn't affect functionality. I understand these are shocks and the price isn't premium, but I expect more from Mitutoyo; like me from Starrett. Good durability if you remember it's not a tool steel - nobody can make indestructible small diameter punches, especially with brass. There is no COO listed so I always assume China if nothing is declared. Overall good value for money.
