PILOT FriXion Ball 3 0.5mm Erasable 3-color Ballpoint Pen 1 pc. Frixion ballpoint pen with erasable handwriting. After the handwriting dries, rub it with the rubber on the back of the pen to erase the color! The frictional heat makes the ink colorless, so there are no eraser shavings, and you can rewrite in the same spot as many times as you like. Three colors (black/red/blue) can be used in one pen, and the lift clip can securely hold even thick documents. The .5mm ultra-fine nib is suitable for fine-writing in notebooks and documents. The body is coated with a gradation of colors, and the metal parts of the mouthpiece and clip create a sharp image. The silicone rubber grip fits comfortably in the hand. *Not for writing certificates or addresses.
