Colour-colored agglomerations are visible, with green blues and greens available for colour management distribution by grade or class in schools. The long-lasting use of alloy blades allows normal use of non-smoking thousands of times, prolongs the useful life of the product and reduces the return rate of customers. A wide variety of pen types, such as crude-calibre triangles, hexagon poles and round poles, can be handled easily, both with standard pencils and with a big pencil for kindergarten. The large volume of transparency crumbs is readily available to observe the amount of crumbs, which are easy to dump without dirty hands and significantly reduce the cleaning burden on classrooms.
