[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] Our unique manufacturing process uses less wood and energy than traditional colored pencils. Our wood comes from sustainably managed forests in Germany (PEFC). [High density and break-resistant] The core is made by a compression process, making it break-resistant and strong. It also produces little core powder, which makes it 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)
