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