Kaleidoscope Materials: Convex Lenses F60, F100 / White Quartz 10mm

Two convex lenses each of F60 and F100, and one clear quartz crystal.
These are materials for making a kaleidoscope.

Purchased from Koji Yamami's online shop a long time ago.

- Convex lens, glass (focal length F60) - 2 pieces
- Convex lens, glass (focal length F100) - 2 pieces
- Clear quartz crystal, 10mm - 1 piece

There are no noticeable scratches, but there are several small chips on the edges of the convex lenses. (Difficult to photograph) These are believed to be manufacturing defects. Please refrain from purchasing if you are concerned.

Thank you.
