I am the owner of a small residential framing business. As I have expanded, I have purchased a bag set for each guy after a year of working for me. I have just purchased my 6th set of bags. They are extremely durable, everything is in a spot that makes sense for a right handed framer. Best of all, they are gorgeous. A guy can go spend $60-70 on a cheap set and toss it in the trash after 10 months or, he can buy a set of these. My personal pouch is going on 6 years no sign of needing to be replaced. The review is asking me for a con for these bags. The only one I can think of is, it doesn't make my lunch for me.
