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.
