These popular Japanese Pilot FriXion "knock" retractable pens contain cartridges of thermo-sensitive ink that can be erased by friction, using the eraser embedded in the top of each pen.
Each Pilot pen writes smoothly and erases without a trace!
... but, put the paper in the fridge, or any place below 10 degrees Centigrade (14 Fahrenheit) and the erased ink will magically reappear!
I love using these pens for my schedules and notes, where I often need to erase, correct or update what I have written.
On the other hand, I would not use them on checks, contracts or legal documents!
This 10-color set consists of of black, red, blue, blue black, green, light green, orange, pink, light blue, and violet
Ballpoint Size : 0.5mm
