A UV Meter For Your Wallet

Carry this in your wallet so you don't start to look like a wallet, and use it to test for the SPF protection the kids need before they turn into bacon bits. Our credit-card-size UV meter measures the intensity of ultraviolet rays and suggests protection in (3) SPF ranges. Also has a window to test the UVA/UVB protection ability of eyeglass lenses. Tests take (20) seconds. (Don't leave this card sitting out in the sun, by the way, lest it lose its magical abilities.)
