Kuretake Karappo Pen, Fine Brush tip 5pcs set, Empty refillable ink pen, for lettering, calligraphy, illustration, drawing, Made in Japan

I have been experimenting with alcohol ink products to create my particular palette of colors. If you draw with commercial art markers, they may be cheap, but they don't last long. And so often, the color is just not what you expected. This product allows you to make your own. Kits of many colors of alcohol ink are reasonably priced and can offer an infinite array of hand mixed colors. The product is inspirational ; and affordable . They are easy to make, but I advise trying the Kuretake ink mixing kit to learn and hone technique. I have been experimenting with the copic marker refills, to produce a color formula of my own with precise recipes so I never run out. I was pleasantly surprised that alcohol ink could work so well. You can buy the pens with your choice of tips. I find the "oblique" metal tip versatile enough to meet my needs. I have not had these for more than a month , but so far they outlast any commercial marker I have used.

I previously bought the fineliner version and loved it. I filled them up with my plain ink. This time I bought the brush pen version and wanted to mix my inks to get different colors. While the inks did end up all over my fingers, the process was so much fun. I flet like a chemist adding drops little by little to get the right shade of green I wanted.The pens works as expected. The ink is ready almost right away. The ink flow is consistent. Although if you rub back and forth too many times on some papers, the paper starts to pill. However, that may be a problem with the paper and not the pen.

The brush tips are functionally identical to the standard tips. There's no actual brush, nor are they softer felt. This renders them useless for my needs, and I've now wasted something like 20 dollars of ink dealing with them.If you're looking to paint with these, avoid. They're only good for writing and line work.

The pens write very nice and it's extremely easy to fill the ink cartridge. You can use just about any ink as long as it does not contain glitter or shimmer (it will clog the pen nib). I think these are definitely worth the money if you have a lot of inks you want to use in a functional way that doesn't involve dip pens or fountain pens. These are a LOT less of a mess in comparison.

These are a pretty good tool, a technical pen nib, with your own fountain pen ink. But I bought the set specifically because the title says "refillable", and they are not refillable - once you fill it with ink, the pen is sealed with the end cap, and the instructions say explicitly it cannot be removed. Quite disappointing.The writing instrument is not bad though. The extra fine nib is extremely fine, and leaves a nice thin but solid line even on textured paper. If you want to draw technical lines on cold press or rough watercolour paper, these would be a good, albeit disposable, option than using more expensive technical pens.

I love to sketch with fountain pens but these markers give me the option of diluting fountain pen ink in water for a wider range of values. For the price, I can carry around as many colors as I want. So far, no leaks. Filling them with ink is a much tidier process than I would have expected.

I bought two packs of these. They were exactly what I've been looking for. I filled them with fountain pen ink in different colors. They absorbed the ink quickly and write perfectly. They're felt tip, fine, pens. I haven't had any problem with any of them. Very easy to fill with ink and work well. I'm glad I got them.

These are nice pens, work great with the intended ink kit.I just really wish these were “refillable”.Refilling CAN be done, but is not recommended.It’s a hack which means they aren’t in perfect shape the second time and you need to source the cores elsewhere. Kind of a bummer, environmentally wasteful and not cost effective.
