Harmony Watercolour: Natural white and suitable for all wet techniques. Harmony is pasted on the surface, without use of jello or other animal derivatives. Its pasting contributes to slower absorption, so pigments stay longer on the surface of the paper, preserving its natural sheen. Liquid masks and masking tapes can be used and removed without leaving residue or damaging the paper surface even after some time. While the paint is still wet, colors can be easily corrected or removed. Pasting used on its surface allows for greater possible corrections and scraping while leaving no residue on the paper surface. Harmony Watercolour is acid free, ph neutral, age-resistant, and vegan. It is available in three different textures: fine, rough, satinated, glued or spiral blocks in sizes: 7x10 inches, 9.5x12 inches, 12x16 inches, 16x20 inches, A3 and A4, in loose sheets in both 20x25 inches and 27 inches 6x39 4mm and roll 5x10m.
