BLOCKX Soft Pastels are handmade in Belgium using pure pigments in the same tradition started by company founder and chemist Jacques Blockx in 1844. Four subsequent generations of Blockx family members have combined traditional methods with modern chemistry to create artists colours that are pure, permanent, lightfast and stable.These water-soluble pastels are soft and velvety in texture, possess a superb tinting strength, and will draw on any surface, although they are best suited for pastel paper. A must-try!
