replaceable refill, roller ball in metal socket, line width 0.4 mm, water-based ink, erasable, rubberized grip, plastic barrel, cap with clip, rubber eraser at the top end of barrel
This gel roller ball pen writes smoothly and softly – maybe the colours are not as strong as those of other roller ball pens but that is not the important factor with this Frixion ball made by the Japanese manufacturer Pilot. Frixion basically refers to friction, which is exactly what makes this pen special – the heat of friction will easily erase the ink after it is applied. That is what the eraser on the end of the barrel is there for! And it never wears out! And on most surfaces leaves absolutely no residue! Check it out!
