This is an excellent paper for almost any media. It has just enough tooth to grab coloured pencil and other dry media like graphite and conte but is smooth enough to create fine detail work with pens like Micron or Winsor & Newton Fineliners without dulling their nibs immediately. Gelly Roll pens also layer nicely and dry moderately, giving you enough time to blend if you need. Similar to all other mixed media pads I've tried, light washes of watercolour also absorb nicely, but too much water isn't recommended. I also found Lamy fountain pens quite nice on here, even scratchier nibs such as the calligraphy nib. With fountain pen ink I did not see any feathering.
My two pieces of advice are: when using really juicy markers such as the Pentel Pocket Brush Pen, you will find slight feathering/spiderwebbing. Its really not that noticeable in the end result, but when laying down the first line I was a little surprised. Secondly, when using Posca Markers you have to be careful to not press too hard or layer too much while the paint is still drying as the paper does start to pill. This isn't an uncommon occurrence for mixed media paper and Posca though.
For the price and the amount of pages you get, this paper is a no brainer
