This Stanley Nail Set tool set is a pretty standard issue, these are the 3 most common sizes I've used over the years with #4d , finishing nails #6d and #8d for routine finishing work. They're imported but appear to be decently made from quality steel and hold up well to the uses they'll receive. Considering how much I paid for Revain here, I'm happy with them and will probably buy them again if the need arises.
