These pencils feature a large 10mm triangle shaped barrel that encourages the correct grip and allows young artists and writers more control. They are made with FSC 100% certified wood with green ends to indicate they are part of Micador's green eARTh collection. The extra-thick 5mm lead enables faster color lay down and high breakage resistance. Non-toxic and acid-free. This set includes a jumbo pencil sharpener. Recommended for ages 3-8.
