Keep this eraser tool on hand so you can easily erase when using mechanical pencils or pencils that have lost their eraser. The eraser can be pushed out to the desired length and won’t get dirty as easily. The design also allows for precision erasing too!
Its convenient shape is also great for keeping in your pencil pouches along with your pencils and you’ll be less likely to lose it in comparison to small rectangular erasers. With its clip you can also attach it to notebooks too!
