Loving this!

As soon as I knew that Pilot finally was coming out with the iroshizuku line of ink in cartridges, I knew I wanted them! I think there is a good portion of pilot users that will understand my problem with the not so great pilot con-whatever-ty converters. The smaller it gets, the worst they are in my opinion. Personally I dont particularly love the namiki cartridges; but they were a good alternative, especially if İ wanted to use my VPs or sterling pens; but still I stopped using them regularly in the end. Now with the iroshizuku line cartridges, it's like I have new pens as well! The supposed to be practical VPs have actually become practical pens! And I've started using (and buying!!) certain pilot pens that I had stopped writing with as well. The iroshizuku line of inks are fantastic, trouble free inks that I loved using in its bottle form anyway. To find most of the colours I love in cartridge form in a beautiful and practical packaging is great. And the name of the ink you're using is written in every cartridge! That's such a small but wonderful touch; I love the fact that it is such an FP user detail and pilot nailed it.. I am very hopeful that the rest of the iroshizuku line will also come out in cartridge form; and I totally recommend these products to anyone who regularly uses pilot FPs, and wants practicality combined with fantastic inks
