The correction tape roller guarantees with its ergonomic shape a most comfortable handling. A recess in the grip naturally leads the user’s thumb to the exact place. The three-dimensional body allows for an especially comfortable and stable hold as the hand is in a relaxed, open position. The shape of MONO ergo defines the angle with which the application head touches the paper. This guarantees that the tape adheres perfectly to the paper and that enough pressure is transferred onto the application head for a clean cutting of the tape when the correction is finished.
