Antique Glass Optical Lense

* One antique optical lense from the early 1900's.
* These are the real deal and are very old. The metal frames have a lovely patina.
* Your lense will be similar to the one in the photo, with clear glass and a "hole" at the top in a cross shape or a slit shape. Some have a slight concave and are not perfectly flat. And some don't have holes at all. If you require a hole, please specify in the comment section at check out.
* Excellent for making pendants!
