Frixion Ball Pen 0.5mm 8-Color Set (Black, Red, Blue, Green, Light Blue, Pink)

This is an eight-color set of erasable ballpoint pens. The ink becomes colorless when you rub it with the included rubber band (no eraser dust is left behind). This revolutionary erasable ballpoint pen defies conventional wisdom. The ink flows smoothly, which is a pleasant surprise. Product number: LFB-160EF-8C
