These watercolor pens are exactly what I was looking for. Super easy to use, very blendable, and no mess (so I can take them when I travel). The colors are vivid when used without additional water, softer when used with water, which makes them excellent for shading.
I’ve recommended them for both student artists and professionals. This pack comes with a fine-point “water brush”—basically an empty brush pen you fill with water to make the paint bleed and blend. There are other additional, wide-bristle water brushes you can buy if you’re doing large scale paintings.
My only complaints are that there are not enough shades of red (only one true red and a few reddish orange colors) and the brush end of the water brush doesn’t hold its shape after a few weeks of daily use. That said, I was able to trim the bristles to reshape the brush and it works perfectly. I wish I could buy some additional reds, but still, I love this set and use it almost daily. I highly recommend it.
