However, there are two (small and negligible) cons and I say the same, it follows criticism at a high level. I love playing with the rubber-holder and these wear out very quickly. In addition, you should replace the eraser time. While one can overturn the eraser, so even if you have completely used up the eraser can not remove. Nevertheless, it is sometimes very tedious, esp. For me has always short fingernails to remove the Radiergummistumpf in this case.
Still, I would recommend this highly enough pencil holder.
