How many people do you know who regret their tattoo? You grow up, you dump (or get dumped), or maybe you picked a tattoo "artist" that learned their craft in prison using ballpoint pens and a sharpened paper clip. At that point, your choices are: deal with it, get it covered up, or get shot with lasers to take it off. And nobody wants to go for a job interview only to be given the evil eye because you're a little more inked than the current employees! Body modification discrimination is a sad fact of life.
What do you do when you want a tattoo but don't want the commitment of permanent ink? The moodInq system is a breakthrough in tattoo technology, using a skin-safe proprietary E ink encapsulated pigment system that lasts a lifetime but can be configured to display any design (or none!) to suit your mood.
So how does it work? We have partnered with leading physicians and technicians in the cosmetic surgery industry to implant the E ink grid, called a canvas. The canvas can go anywhere on your body and be configured to the size and shape of the body party you'd like to ink. After a short healing period (usually 2-3 days), you can begin using the moodInq software included with your kit to change your canvas to display the tattoo you desire!
