I just was given a pair of fingerprint m frames by my dad that he has had for the past 20 years but he let me have them bc he hasn't worn them in a very long time n he no longer wanted them. I was just hoping that someone on here might now something about them? What are they worth? Ive tried finding info about them but im struggling the only reason I know what they are exactly is bc of o-review. Any help would be awesome.
