Enamel steel box, protected by a felt pouch with watercolours BLOCKX tube 5ml. BLOCKX extra-fine watercolours all have a degree of exceptional light resistance (note of 7/8 on the BWS international scale). Composed of rare pigments, very finely ground, coated with arabic gum and honey to strengthen the color resistance over time and give them more shine and brightness, the BLOCKX watercolours offer a shine and a smooth texture.
