Have used this paper only once but so far I'm happy with it. This Baohong paper compares well with Arches though it seems to be a little more absorbent. Wet washes work well. i think for wet on dry I have to use a little more water than I usually do . It handles lifting and scrubbing really well without damage. It buckled slightly while wet but smoothed out when it dried. I will buy this brand again...
