【Fabric Cover】The cover made of high-quality fabric not only looks elegant, but also feels soft and delicate, giving users a pleasant tactile experience. 【Hardcover & Portable】The unique lock line binding technology ensures that the watercolor book can be completely laid out, providing the artist with more creative space. This design is not only easy to carry, but also can be easily spread out in outdoor sketching or traveling, and enjoy the unfettered creative fun. 【Cotton Material】The selection of long fiber cotton material made of paper, with high density and flatness, can effectively reduce the deformation and wrinkling of paper. Suitable for all kinds of watercolor techniques, whether it is fine painting or large area rendering, it can perform well. 【Professional Drawing Papers】The paper of the watercolor book presents the bright colors of the watercolor pigments, making the work look more vivid. At the same time, the paper has good water absorption and ductility, ensuring the natural transition between colors, and the color stacking effect is particularly excellent. 【Dual-sided Design】Each page can be painted on both sides, which increases the practicality of the album.
