Stone Pen

Not bad

The pen has a nice weight to it without feeling bulky or clunky. For the price point, I expected a much better writing experience. It does feel smooth, but it doesn't always have a fully saturated ink pattern for me-not quite skipping, but not "juicy" either. It works fairly on Karst paper, as intended. I'm just as likely to use my uniball signo, however, and would probably not repurchase for that reason.

Falls short of expectations

This is a decent pen, however I’m unimpressed overall. It’s nicely weighted and has a very pleasant matte finish, yet the oversize barrel is almost too large and the obnoxiously wide pocket clip can be intrusive when writing. Its “Floating Ball” ink cartridge is reasonably smooth but looks and writes just like any other good quality medium tip ballpoint. (The one I received actually writes on the fine side of medium, imho.) Either way, its line width is definitely not 1.0mm as stated on Karst’s website. Although this ink outperforms gel pens on Karst Stone paper as claimed, it performed no better than other ballpoint inks I tried on Karst Stone paper. From my perspective, Caran d’Ache 849 ballpoint pens (which are also Swiss-made, btw) offer a better overall value despite their modestly higher price.

Just shy of perfection!

I love the feel of this pen in hand and it does noticeably cut down on ink smear! All around, this is a solid product and a great choice if (like me) you have made Karst planners a necessity.
