The high-quality ONE4ALL Professional Sketchbook was specially developed for alcohol, water and acrylic markers. In addition to its high-quality hardcover back, it has a black picking belt and orange endpapers. The cover has an embossed ONE4ALL logo. SPECIAL ANTI BLEED COATING The paper’s (150 g/m²) special coating ensures sharp edges and prevents the ink from soaking the paper, which can thus be used on both sides. Next to high-value applications and artworks (mixed media) the ONE4ALL acrylic color system is ideal for the design of ornamental items on nearly all surfaces. Quality restrictions and a loss of color characteristics might appear when using unclean or wrongly prepared surfaces. Generally a previous check of the color on the chosen surface at a discreet place is advisable. Please note that absorbent, flexible and uneven surfaces are naturally more unsuitable for paintings than smooth and unabsorbent surfaces.
