Black Paper Watercolor Sketchbook — 300gsm Cold Press, Acid-Free

This watercolor sketchbook is built for artists, illustrators and creative professionals who need paper that can take bold, layered work. Sheets are 300 gsm cold press stock with a subtly toothy texture, so pigment, ink and mixed media sit on the surface without buckling. The book is supplied by Longgang Haha Stationery Co., Ltd. in China.

The black tone of the pages changes the way a watercolor sketchbook is used. Light tones, metallics and white highlights come forward against the dark ground, and opaque inks hold their opacity. Gouache and acrylic markers layer cleanly, while gel pens and coloured pencils leave crisp marks that stay readable.

Because the paper is thick and acid-free, finished pages stay flat and resist yellowing over time, which matters for portfolio pieces that need to be kept. Cold press texture balances absorbency and control, so washes settle without sinking away instantly and dry media keep their character.

The book carries 80 sheets in a hardcover, spiral-bound format that keeps the watercolor sketchbook secure through repeated use. Minimum order quantity is 500 pcs, and pricing is quoted on request.
