Enhance your artistic experience with the Derwent Graphite XL Blocks Tin of 6. This versatile set includes a range of degrees from hard to very soft, as well as an onyx dark block. Each block offers bold and agile marks, with the strength and body of a chunky pencil. You can also experiment with grating or cutting the blocks, allowing for detailed and textured effects. The water-soluble formula adds even more flexibility, as you can use the blocks for broad coverage or expressive mark making. The ergonomic design of the blocks makes them comfortable to hold for large scale drawings, while the high volume of formula in each block is equivalent to 8 standard pencils. Whether you're looking to add fine details or create atmospheric and tonal artwork, the Derwent Graphite XL Blocks are the perfect addition to any artist's toolkit.
