DESCRIPTION

I have been given a lot of vintage tools and gadgets from a friend who helped clean out an estate. Aparantly the man was some kind of micro engineer. Researching as much as I can but with some items the info is limited.

The only information I could find of a box of crayons that looked exactly like this was a picture titled as National Camera Engraving Wax. I'm not sure if National Camera is the brand or if it's for cameras lol.

All info I could find is below. Apparently they are used by opticians.
