The problem, the buyer! There are two versions of the "Perfect Pencil" - which is a version of a pencil sharpener without extension (slightly cheaper in price). The other version is that the pointer - which is something more noble and expensive. Sorry, the offer of Ersatzbleistife for the "Perfect Pencil" does not say that the pencils for the version without sharpener are. They do not fit perfectly into the other version.
The Bleistife themselves are good and delivered quickly - I could not use unfortunately as planned.
