Cellphone Strap Cellphone Charger in the Shape of an Eraser

Only Japan could have come up with this item: a cellphone strap that's not only shaped like an eraser, but houses two AA batteries and is actually a phone charger.

Unfortunately, the only phones that can be charged with this thing are from FOMA and SoftBank—both only available in Japan—but we're sure somebody can come up with something similar for US phones. Get to work, crazies!
