This Radar Light eraser is easy to use and pleasant to look at! It comes in a colorful variety of light colors with cases to match. It erases smoothly and thoroughly with a light touch, and due to its soft quality, the shavings are clumps rather than messy dust. The case is well-designed too. While erasing, the corners of typical eraser cases tend to dig into the erasers, causing eraser nicks or breakages at those contact points. To prevent this, the Radar Light case has notches in the corners that disperse the pressure between the eraser and case, thus reducing nicks and breaks.
