In Kutsuwa's "Zikeshi" series, new pen type has appeared! It has a slim body and is easy to hold. "Zikeshi" is an eraser dust sticks to the magnet. It contains ferrite (iron powder), and you can collect the eraser dust with a magnet. Since the pen cap has a built-in neodymium magnet, you can collect the eraser by sticking it to the cap. The cap has a knob, and when you pull the knob on the trash can, the magnetic force is turned off and you can throw it in the trash can with one touch. Also, since it has a built-in spring, the knob will automatically return to its original position when you release it. In addition, the pen type eraser has a small diameter of 5 mm, so you can erase even the smallest details.
