Here's a reason to keep a home printer around! Inkjet Tattoo Paper lets you design custom temporary tattoos, which is great when those 50-cent jobs from the gumball machine won't cut it. Think of how great these would be for theme parties and costumes (these are way better than just whipping out a Sharpie for that Jeffrey Sebelia neck tattoo or your Kat Von D impression).
You only need soap and water to remove these, unlike regular temp tats — which I'll gamely sport for a pirate party, but come Monday, I don't want a speckled mess of colors encircling my arm at work. I don't know what kind of theme party this necessitates, but I would so print out and slap on an Apple tattoo or a Gameboy tramp stamp!
