This is one of the Glow-in-the-Dark Power Button Symbol Charm Necklaces I make.
The charm is completely handmade of polymer clay and painted with metallic acrylics. The charm is about one and a quarter inches in diameter. The symbol in the center is carved, as well as painted, for added depth and a more realistic feel.
This was kind of a commission for my brother-in-law who usually thinks my geeky crafts are well, just for nerds, but he thought this idea was so cool, he had me make a special silver one on a keychain just for him. I think it is pretty neat myself, I have a shirt with a glowing power symbol on it that I love, but it's starting to wear out, so I thought something like this would have the same effect, but as long as I don't put it in the washer, it should last a long time!
