About this Product
This is a 10 cm rulered bumper for iphone 4 and 4s. When you look at the screen, the right side of the bumper is ruler and it has a smooth line below to draw lines. The left side is empty as you can see. I devoloped this product for myself at the beginning because even if i leave my ruler at home, i can design a product ,measure it with my iphone and then upload to shapeways! :)
