My second fountain pen was a Kuratake 13, and I love it! I’ve been using it daily for more than a year and had no problems with it at all. I’ve used it with Diamine Ancient Copper, Robert Oster Deep Purple, and Organics Studio Santiago’s Sea. The only thing to be careful of is that it will get your fingers inky for the first week or so after a refill. The breather holes are above the brush and they seep for the first seven to ten days.

Mine only does that the first day when I write after filling it.
