Bergeon 2611-TN 6.7X Watchmaker Loupe Biconvex Air 1.5

very good optics, very light weight. easy for your eye to hold it. related item however, a separate order, the wire to hold it on your head, nothing but problematic for me. should not need instructions and it did not come with any, but then I had a hard time fitting the loupe onto the wire, and then once I did it was not comfortable on my head. the loupe itself is excellent. the holding wire was subjectively problematic for me, not sure if that is all me or the wire holder itself. Also I might have been happier to get the loupe with 2 lenses for lower and higher magnification in one loupe.
