Kuretake ZIG Karappo Pen (Empty) Brush Tip 5/Pkg-CF060452

Ink soakage was difficult but with the right ink, the pen worked well.

Great length

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.

I like the idea of having a reusable and refillable liner pen. To lessen my impact on the environment. However, this one is meh. The "brush" nib is very stiff and the ink flow is spotty, no matter how long you soak the sponge. It's good in theory, subpar in practice.

These are not brush pens; they’re more like a felt til pen. That said, they hold a lot of ink, are easy to assemble and the ink flows well when using them. I have only used them with alcohol based dyes, which are very thin, so a thicker medium may not flow as well.
