Thanks to its ribbing on the container, it sits well in the right hand and ensures relaxed, controlled sharpening without contortions. Inside: a robust magnesium sharpener for maximum precision. And it does so twice: the Groove reliably shapes both 8 mm and 11 mm pins. Ideal for pencils and colored pencils of all kinds. With the hole closure, the chips stay where they belong and it sits reliably tight, even loosely in the school bag. In addition, there is a look that is worth seeing: four transparent colors that give you a glimpse inside. Equipped with Dynamic Torsion Action® to prevent the pencil tip from fraying KUM blades of the highest precision Magnesium sharpener for constant precision during sharpening Suitable for 8 and 11 mm pencils With dust cap Made in Germany Especially for left-handers
