Those of us who often use both pen and pencil (or a pen + pencil multi pen!) will find that the Tombow Mono 2way Correction Tape + Eraser is the perfect all-in-one correction tool. One end has a slide-out correction tape head, while the other has a twist-out eraser. Both can be retracted when not in use, ensuring protection against damage. The correction tape and eraser are refillable.
