I've been using this pen for a long time and its really nice~ I was looking for gel pens but most of them would bleed through the paper or they are not smooth. But this one is just right! Because its 0.38, it will not bleed through the paper and the writing looks neat. It dries fast ,so left-handers, you can avoid messy smudges all over the paper and on your hands :) So I have tried out a few colours other than black and blue, and most of their colours are really bright and unique. When my ink runs out, I'll just get the refills [picture]. And also, the pen looks simple and nice. The only annoying thing is that I have to get new refills after the pen drops on the floor (because the ink would not come out after that or the tip would break and ink would spill out) :( But other then that, (which can be prevented) the pen is great.
