Here's the first test with Shinhan touch markers. First thoughts, great for the price but the Letraset Tria pens blend like a dream. These are more like Copics on the blending front. I need to give them a proper work out and get used to the tips. The fat end isn't just flat, kind of a rounded flat (if that makes sense) - the fine end is nice a tight though.
Above is a quick colour test using 4 colours - nice enough, but would have liked to blend the darks better, this may be my lack of skill with the different shaped chisel nib.
