Judging from the box, these are from the 1970’s, but could be earlier or later, just my guess.
Heavy Weight, they are about a pound + each, high quality, like the tools.
Even though the original box looks rough, the glasses are clean and in good shape.
My guess, a guy bought them, wife said NO, and they stayed on a shelf in the garage.
Would of course make an excellent Man Cave - Garage Bar addition which is what I am going to do with them if they do not sell.
They make newer versions, from China of course, I believe these early ones are US made like the tools.
I’m a huge Snap-On tool fan, so not even sure why I am selling these, but I have a lot of stuff.
Thanks
