I have been searching for the ultimate watercolour sketchbook for years and have always been vaguely dissatisfied until now - I love the Baohong pads and blocks so had to try the sketchbooks - the paper is brilliant and performs perfectly with minimal warping even with heavier washes. The books themselves are things of beauty. Delighted with this find and will be buying more. Excellent service again from Senior Art - ordered them one day and they arrived (interstate) the next.
