• This is a three-color ballpoint pen that uses "friction ink" that can erase handwriting with frictional heat.
• The ultra-fine body has a maximum diameter of 12.8 mm, and the tip shape is smooth so that it can easily fit into a bag, suit, or notebook pen holder, improving portability.
• The clip uses a lift clip that will not break even if it is clamped 100,000 times. Handwriting can be erased smoothly by rubbing with the erasing rubber at the back of the pen.
  
• This is a 0.38 mm ultra-fine type that is ideal for those who prefer fine writing or writing in small areas.
