Nah, we're not surprised in the least that the zany gurus at SolidAlliance have found a way to crank out yet another completely bizarre USB-related gizmo, and the Xstamper USB thumb drive / stamp hybrid certainly fits the atypical bill. Reportedly useful as a type of Japanese notarization device, the stamping abilities of this 256MB USB drive allow "official stamps (ahem) of approval" to be handily applied without forcing you to hunt down your dedicated depressor. Of course, the snazzy carrying tube and quarter-gigabyte of internal storage just about top off the amenities, but if you're looking to add one more off-kilter device to your keychain assortment, SolidAlliance's latest can be snapped up now for ¥3,790 (or about $32).
