Kitpas 'Eco Friendly' water soluble washable Block Crayons can be used on a variety of surface from baths, mirrors, windows to paper and card. The block shapes make them perfect for sketching or writing with thinner lines or or for block shading. Paint over with a wet paintbrush or use them as blocks of paint for a watercolour effect. Then they wipe off hard surfaces easily with a wet cloth.
