Henna is great for temporary tattoos that last for a week or so, but you’ll still have to come in and have someone draw the design on your body. Like henna, the Inkbox is a temporary tattoo that can last for much more than a single day. Unlike it, you can simply slap a design onto your body, similar to the temporary tattoo decals children stick on their skin.
Using a patent-pending ink formula derived from the fruit of the Genipa Americana, the temporary tattoo can hold fast for up to two weeks at a time, giving you a design with the longevity of henna and the convenience of a tattoo decal.  And, yes, you can take as many showers as you want during those two weeks (thank God) without ruining the tat, which can be a good thing (if you like the design) or a bad thing (if your friends stuck it on your forehead).
Each Inkbox tattoo comes in the form of a four-layer stick-on pad that contains the ink and the stencil of the design. To use, simply place it with the stencil facing down on the skin, dampen it with a wet towel for 10 minutes, and peel the pad away. Done. The pad, by the way, can be reused once (second application will only last up to 10 days, though), so you can tattoo the same design elsewhere on your body.
Currently, they have 300 designs available in seven different sizes each and accept custom designs, so you can use it to test-drive that doodle tattoo before getting an actual one. Catch is, the ink only comes in one color (black), so you’re restricted to outlines and block designs.
A Kickstarter campaign is currently running for Inkbox. Pledges to reserve a unit starts at $18.
