I LOVE this watercolor set for impromptu plein air painting. I keep this one in my bag with a small watercolor journal, so I always have it handy when going to the dog park or when relaxing at our local coffee shop. The quality of the paints was so much better than I ever expected from such an affordable set. They aren't professional quality, but they definitely perform better than most student grade paints. The paints are easy to use, the colors are very pigmented and they perform very well on paper, blending nicely. The size is compact, (about the length of a ballpoint pen) but it holds a surprising amount of paint. The layers come apart and twist together to form a very sturdy paint set-up. A watercup and mixing palette are stored underneath and neatly snap in place. And, the travel brush that's included is exceptional! Usually, the brushes you get in sets are cheap and poor performing, but this brush performs almost as well as some of my very expensive Kolinsky sable brushes. And, its a nice weight. What a wonderful surprise that was! I'd buy this again for the brush alone! My only complaint would be that a couple of the paint stones were loose in the pan and easily fell out in the beginning. But, once I used the set several times, they stuck in the pan.
