CASE FOR LENSES

THE CASE FOR LENSES

At small works use a magnifying glass, placed for convenience in a frame of vinyl plastic. In a square plate, 4 mm thick, cut a circular window with inside recess (groove) in which the lens is held securely enough. And for protection from scratching the glass rolled leather sheath in which the plate is secured by a rivet. In the plate made a few cuts-snags — thanks to them, the lens is easily removed from this soft box.
