I been using these markers for a while now and I got to say, these are really cool! I never have used alcohol based markers before and as a beginner, these help get into the world of alcohol based colors without having to spend so much for just one copic marker. It isn’t without its merits though. I haven’t used all the colors yet, but when I was swatting the colors, I did come across some of my brush tips being stiff. No matter, I can work around tgat. I am disappointed that the smaller 48 pack didn’t have at least a one skin tone marker (R18 or R19) as I like to use that set for portable transportation over carrying the 120 set. I do own the skin tone set at least, but I didn’t have it with me at the time so I had to work on something else. There is a bit of streaking time to time, but I think that’s just me being a digital artist who have to go back to the traditional roots due to a lack of a computer (I’m on mobile). Otherwise these markers are really good bang for buck, and I have recommended to friends who are also artists too. Also don’t mind the quality of the pics, my room has the worst lighting.
