This 123ink ballpoint pen writes smoothly with blue erasable ink. The special ink disappears by hot friction. You can easily correct any errors with the plastic back of the pen. You smooth out the ink by rubbing it and you immediately write the correct text in the same place. So you don't need an eraser or correction fluid and you can make corrections without paper damage. Thanks to the point width of 0.7mm and the writing width of 0.35mm, you can work accurately and in detail. The ballpoint pen has a loose cap with a handy clip.
Of course this 123ink product also comes with a 100% warranty!
