The friction ball is a revolutionary ballpoint pen that can erase written letters. Even if I miss writing it is a ballpoint pen that can erase cleanly and write again in the same place. After the handwriting dries, the color disappears when rubbing with the rubber at the rear of the shaft. Since color is made colorless with frictional heat. you can rewrite it in the same place as many times as you like.
Size Pen : 0.5mm
