Review: Koi Watercolor Brush Pens 12-Color Set

Koi Coloring Brush Pens

I was introduced to the Sakura Koi Coloring Brush Pens 12-color set ($27)  by way of Lisa Condon’s blog, Today Is Going To Be To Be Awesome. She had a post on her sidebar about her favorite tools to use for drawing and illustration and one of her recommended pens for sketchbook use were the 12-color set of Koi Coloring Brush Pens.

The pens are felt-tipped and shaped like a paint brush tip. The colors are bright, clean and vivid and are water soluble so they will blend together easily allowing the 12-color set to extend itself into a wider range of colors by blending the colors together.

If you do blend the colors together, be sure to have a piece of scratch paper handy because the colors will migrate from pen to pen and you’ll want to clean off any color transfer that might occur in the process though this can also create some interesting an unexpected results. Just be prepared.

The set comes in a plastic sleeve but I prefer to dump out all my pens immediately into a pen case or a cup so they are handy and accessible. If they are all locked away in a protective sleeve, I find they don’t get used which is a waste.  Rolling around on my desk, I wrote notes, doodled, colored and generally just enjoyed the bright vivid colors all week which was welcomed in the bleak January days I have to say!

The black pen in the set is also water soluble so I would not recommend using it as an outliner and then trying to go back and fill in with colors as the black will migrate. The word “KOI” on my sample has darker colors because the black started to creep into the center. If you want to do outlining in black brush pen and then use the Sakura Pigma Professional Brush pens instead which are permanent and then add color with the Koi Coloring Brush Pens.

I think these pens might spend a little time out with our coloring books this week and see how it plays there. I’d also like to add in a little light water brush to lighten the colors a bit and help to blend so that the colors will play even more like watercolor. I did try a water brush after photographing the samples and the colors do continue to blend even several hours later so these will definitely be lots of fun to play with. A very clean, portable way to use watercolors on the go! And, wow! Are the colors ever bright and clean and juicy!

  1. Interesting! These might be excellent for use in a Hobonichi,where watercolor paints are ok but crinkle up the page.

    1. The PITT Artist brushes are permanent inks while the Koi Watercolor brushes are water soluble so that is the biggest difference. So far, I have not used them long enough to determine which has the longest point longevity but I find that the PITT brush tips wear out very quickly. You can flip the PITT tips over and use the other end if you pull them out gently and get a bit more mileage out of them though.
