I looked on them and they don't say where they were made but they are made well with raised panel looks like Craftsman,Bought them from my Matco dealer
Here's a 6 piece large size set, they look identical to what you're offering, and this is going for $40. I understand you have a 10pc set, but still, what you have is definitely not worth your asking price.
How do you figure? You add 4 wrenches and shipping on to that set and you justify an extra $75, how? No way those wrenches would cost any more than $25 to ship, so you figure you actually getting $90, I could buy that set brand new shipped to my door for less. Sorry man, just trying to get you to see the facts.
