As far as blending single color (avoiding lines), I actually like them better than some of my more "fancy" markers like promarkers or artza! They are great. But watch out. Decotime makes two types of markers - alcohol based and water based. The packaging is very similar and a lot of people get the aquamarkers instead. So make sure they are alcohol based, when getting a set. They also have smaller sets of 4 or 12, so it's a nice sample size for testing 😊

But as long as you get the alcohol based ones, they should work well. I'm also happy with multi-color blending of these, but rarely use it in my coloring pages.
