Titanium Keychain Glow Fob V3

This is cool!

Good quality, the sky blue one lights up more than i thought it would. I fully disassembled it and used a torch to oxidize the titanium in pretty colors. Worked out great. I am using a UV light to show the color in daylight. It is completely clear and uncolored in full daytime brightness. But it also lights up the floor from waist height in a pitch black room

Pretty nifty light 😎
