Knowledge of erasers

The reason for the cut of the corner of the sleeve

It is to prevent the corner of the Plastic Eraser body from bite to the sleeve even if the Plastic Eraser is pushed out by a considerable strong force and the character is erased. We call the processing of this sleeve “U-cut”. The Plastic Eraser sleeve is designed to be easy to use by reinforcing the moderate flexibility (deflection) that adheres to the Plastic Eraser paper. The flexibility of the Plastic Eraser takes into account the relationship and provides a comfortable feeling of use.
