Want to be the coolest cat around the fire? Get yourself a rad tumbler or mug.
Sick of loosing your tumbler in the dark after a few too many? Get yourself the Glow in the Dark Tumbler! Use it during the day and allow the sun to charge it, then watch it glow once the sun goes down!
Glow In The Dark Tumblers:
White ----> glows green
White ----> glows blue
***Glow Tumblers must be "charged" (by sun or bright lights) in order to glow.***
