These lovely French opera glasses are in perfect working condition. The metal looks to be brass but can't say for sure. The eye pieces are stamped LeMaitre Paris. The original case is quite worn but still very much intact. It is lined with aqua silk and the closing mechanism works perfectly. The glasses are 3 3/4" wide at the lenses and 3 1/2" at the eye pieces. The height is 2 1/8" when they are closed all the way. The mother of pearl is in very nice condition. There is what looks like a tiny crack or chip on the right eye piece but that may just be the nature or the shell.
