The STABILO Woody is a colored pencil, watercolor, and wax crayon all in one. The extra-thick break-resistant 10mm lead comes in 18 rich, highly-pigmented colors that work well on light and dark paper, and are especially suitable for small hands. The lead is wrapped in a pencil-like wooden barrel, preventing the lead from breaking into pieces like traditional crayons. These pencils are a joy to use, offering fatter, broader color than a standard pencil and are more convenient and less messy than traditional wax crayons. The chunky lead has bright water-soluble pigment, and the large diameter wooden case is comfortable to use. Non-toxic. It can also write on glass and most surfaces, making it frequently used in commercial settings for marking non-porous materials for cutting as it wipes off easily. Sharpen with a Woody Sharpener, available separately. Experience 8 times more color than a traditional colored pencil with extra color intensity, even on the darkest papers. Due to its chunky shape and size and indestructible lead, it's perfect for children's hands and promotes a good grip. Be creative on all smooth surfaces like glass, plastic, and leather, and wipe it off easily. Available in 18 rich colors.
