I had a pair of glasses that had some issues. I sent them back for warranty and the decided to replace them but that model was discontinued so I picked out a new pair. They showed up today, I tried them on and there too wide for my face. So back in the box they went.

Strangely enough I have another pair of very lightly used glasses I'd sell if someone is interested, I just dont use them. There called the Smith Interlock 01. They have a polarized light gray lens with a black frame. There used but there are no scratches or signs of wear on these. $60
These ones are discontinued but this is what they look like.

If no one is interested In the next week or so I'll take these off and put them on Ebay. Thanks
