These Lyra Aquarell Colour Pencil Sets are professional water-soluble pencils. They are packed in metal boxes, and suited to all drawing techniques. They come in a range of intense, bright colours with highly light-resistant pigments. Thanks to the giant water-soluble lead containing wax pigments, the pencils can be mixed and blurred like watercolour paints. As they are highly soluble, it is easy to achieve excellent transparent effects.
