The Lyra Rembrandt Graphite Aquarell offers the perfect blend of traditional sketching and watercolour techniques. These highly durable pencils produce fluid, precise lines that can be blurred like a standard graphite pencil. However, once water is applied with a brush, the graphite dissolves into a smooth wash, perfect for adding depth and dimension to graphic work, architectural designs, and fine art. AP certified as non-toxic and available in three versatile grades.
