The Pilot Hi-Tec-C pen is remarkably smooth, which surprised me because I had been used to the mantra that thicker tips write smoother. As I understand, there's a tradeoff that as you go to a thinner tip, you have to sacrifice smoothness. Poorly made pens with thinner tips can sometimes be pretty scratchy, so much so that I'd gotten turned off to thin-tipped pens. The Hi-Tec-C, however, defies the laws of pen physics as the tip flows across the paper with ease.
My girlfriend has the 0.4mm Pilot Hi-Tec-C Putimo. She offered it to me to try it out as I had initially complained about the 0.3mm tip of the Hi-Tec-C. For me, the 0.4 is a nice compromise between precision and thickness. Perhaps if I get another Hi-Tec-C it'll be a 0.4, but my mind isn't as closed as it once was on 0.4 mm and thinner pens.
Of course, I haven't yet mentioned what makes this pen "the cuteness." Well, the pen came with a Hello Kitty figurine adorned on the top of the cap. (The Limited Edition Hello Kitty Hi-Tec-C). The figurine is removable and transferable to other Hi-Tec-C's so if you're not the Hello Kitty type but know someone who is, you can always give it to them. Speaking of gifting, these pens would be a perfect gift for your niece/daughter/girlfriend with a special liking for anything Hello Kitty; they're super cute and, as an awesome added bonus, they write excellently!
