We have the sharpener from Faber Castell here and to the lead / and crayons and colored pencils of Staedtler, who were already in the spring bag purchase. What struck us; The sharpener from Faber Castell is only suitable for its crayons that of Staedtler he pointed choppy and dull from, while also the holder at Faber Castell quickly opens and the whole Anspitzermüll fall out. Then we bought the sharpener of Staedtler. Both the same size, (For Schlappermäppchen a bit too big) but the Staedtler- sharpener gets you both sharpened colorful soft. Own company, as well as the crayons from Faber Castell, minor nuisance, the sharpener of Staedtler be very hard to open to unlearn it, but otherwise perfect!
