I gave these as a Stocking Stuffer to my Wife because she loves puzzles. The glass is thick and they are of decent quality for the price. However, the pair is not matched at all. In other words, one is colorful with vibrant pinks, purples, blues and greens just like the photos. The other is literally top half blue and bottom half silver. Not worth retuning, She wore them once (to make me happy I guess), but they are heading for eternity to the junk drawer. What a shame.
