Our innovative design makes the SonarPen a battery-free device so you'll never have to discard it. It will also works with all iPad models produced over since March 2011 (all except iPad 1st gen).
The magnetic pen holder attached to the back of your iPad with a piece of 3M double side tape. Installation is super easy and it doesn't leave any dirt on the iPad when you remove it.
The pen is one of the first tools we learn to use as a child, so creating with a pen is second nature to us. Using SonarPen, we can do all these tasks easily like using a real pen: lettering, digital painting, urban sketching, note taking and doodling. Cause SonarPen let you control the strokes on the screen by sensing the pressure from your hand.
