[Recommended for detailed coloring] The core is hard to break and has just the right amount of hardness, making it ideal for detailed coloring. [Sustainable & Upcycled] Our unique manufacturing process uses less wood and energy than traditional colored pencils. We also use wood from sustainably managed forests in Germany (PEFC). [High density and break-resistant] The core is made using a compression process, making it strong and break-resistant. It also produces little core powder, which is less likely to stain the paper. [Recommended for gradations] The gentle colors make it easy to create gradations and other shades. [Ages 3 and up] Made in Germany and meets European safety standards (EN-71)
