It wasn't the smartest purchase I've made, a bit frivolous, but it was only a few dollars more than the standard stickers -- and they do serve their purpose... I'm not sure what I was expecting... did I expect their glow to fill the entire room with light or something?!?! :D

Hopefully it doesn't contain plutonium or something crazy, I don't want my finger tips to melt from the radiations :D :D :D
