LYRA artist supplies are superior products for serious artists, young and old. LYRA developed the color assortment of the LYRA Waldorf Selection Colored Pencils in cooperation with the renowned Waldorf School. Each set includes an exclusive selection of unlacquered Super Ferby Pencils, which feature a large triangular shape and a comfortable grip which is particularly suitable for beginners and left handed people. Giant 6.25 millimeter cores are extremely break resistant, wear for 3-4 times longer than standard colored pencils, and require less frequent sharpening. The pencils have a closed end so the core is not exposed and natural, unlacquered wood for very young children who may put the pencils in their mouths. These pencils are wide and strong for extra life, are AP certified non-toxic, and come in a convenient pack of 6.
