These pads are mould-made with 100% cotton French watercolor paper. This paper has enhanced surface cohesion to allow for the application of several layers of paint without damaging the paper surface. Special mass and surface sizing allows even and easy pigment spreading as well as strength when wet. Moulin Du Roy has very good dry and wet erase-ability. The cold press surface is neither too smooth nor too grainy, making it easy to handle. Each pad has 12 sheets of 140 lb./300gsm watercolor paper.
