These handy little erasers from Japan are a total life saver! Made of natural rubber latex mixed with a very fine silica grit, this eraser can be used to lighten or remove ink marks, including ballpoint, rollerball and some marker, from a variety of surfaces. Also works for notoriously difficult-to-erase colored pencil marks! With its tapered edges, this eraser can be used for fine details. Great for creating a weathered vintage look on ink drawings. This eraser is also perfect for those who favor colored pencils as it removes colored pencil markings with ease. A real fan favorite!
