Precaution for Use

· The eraser is extendable as long as the cap can be twisted smoothly. Twisting forcedly may damage the mechanism.
· The eraser may break if extended too much.
· Avoid writing with the pen tip pointing higher than the end. This may cause the ink to leak.
· Avoid exposure to direct sunlight and high temperature when storing.
· Retract the pen tip when carried or not used. Leaving the pen tip extended when not in use may cause stains on clothing and other materials.
【! CAUTION】
· Be careful when handling the pencil as the tip is sharp.
· Keep it out of the reach of small children.
· Do not put the eraser, tip, and other parts in the mouth.
· Do not use it for any other purpose than writing.
· Do not use the eraser for any other purpose than erasing.
