Hahnemühle 灰色書籍（A4 尺寸，炭灰色，40 張）

The stitched binding lays completely flat, which is perfect for keeping my ink sketches from smudging across the spread. At 120 gsm the paper has a lovely slight tooth but still takes a fine liner without any bleed through. Forty sheets feels generous for the price too.
