I’ve had this for about a month now, and I can definitely say that it works incredibly well with my copics. Colors blend very nicely, and I don’t deal with the issue of them bleeding outside of the line work very often if at all. I had originally been using regular sketchpads for my drawings, and while it worked it wasn’t ideal. Lots of bleeding out of the lineart and sometimes colors not mixing well. I was initially nervous to buy a marker pad specifically for markers as I had a bad experience with one in the past. I can say whole heartedly though this is a great marker pad, and I definitely recommend for anyone who’s looking for a new sketchbook for markers.
