Hahnemühle 素描日記本（A6 尺寸，黑色，60 張）

The paper handles a fine ink pen without bleeding through, which surprised me for a sketchbook this thin. It slips easily into my coat pocket for quick coffee shop drawings.

The A6 size is exactly what I needed for quick lunch-break sketches, and the black cover hides the inevitable coffee stains pretty well. Paper holds up to ink and light washes without bleeding through, which is more than I expected from a pocket-sized diary.

Fits perfectly in my jacket pocket, so it’s become my go-to for quick urban sketches during lunch breaks. The A6 size feels just right, and the black cover stays clean even after being tossed in my bag for a week.
