UV Mini Flashlight

I buy these in bulk for about $2.00 each. They are dependable and work every time. I box most of the special rings that I give away. I take the original ring, zip-lock envelope, and put a Keychain UV light inside, then tuck it into the lid of the box. That keeps the light in place for the new owner to find.
I was a cut-and-fit inlay person until last year; the glow rings converted me halfway, and I still like to place individual pieces of crushed rock and opal. The glow powder makes the ring special.
