A friend gave me a piece of gear that I could not identify. He had bought it in a collection of optics at a garage sale and didn't want it.
So I went to Google Search and typed in JJC 55-6 and couldn't find any information. Then I put my reading glasses and realized that it actually read JJC SS-6

This is a loupe for inspecting digital sensors for dust. It seems to work pretty well...
Can't beat the price either...
