Pen-style erasers are becoming increasingly popular because they are convenient, mobile, and ergonomic. The popular AIN eraser now comes in a new triangular holder form. The triangular shape was purposefully chosen to address two eraser functions. The wide sides can be used for the erasing of large areas, while the three corner points can be used to erase areas requiring more precision. Each holder contains a generous amount of eraser, and eraser refills are available. Just press the top cap to extend more eraser. Holders are available in metallic red, blue, green and purple colors.
