The Braille Pen

In order to make handwritten notes, sightless people must use a slate and stick to poke holes in a piece of paper. They must write the letters in revers so that when the paper is flipped it can be read form left to right. The braille pen replaces the traditional way of writing braille by dispensing little plastic dots with an adhesive backing onto any paper. The design holds hundreds of dots at a time, before needing to refill. It's discreet design allows for a sightless person to look like they're just using an ink pen, and not a specialized device.
