Clean Line

When cleaning, do not press the eraser too hard on the surface ( this action will stop the rotation and damage the device).
Gently move the eraser left and right on the surface or up and down to erase all the parts you need.
To erase targeted areas effectively and precisely, great eraser for mechanical & graphite pencils.
Do not put small pieces in the mouth to prevent accidental swallowing.
If you do not use an electric eraser for a long time, remove the batteries.
