Good idea, with quirks

In three of these parts of my Spitzer is chipped from the outer casing. Even with little pressure then the Spitzer falls into the collection container. And I have not used the Spitzer excessive. Until that happened, the Spitzer was really handy. There is a version with cover - an eraser, which closes the two holes. Then no more dirt can fall out of the sharpener. One should better connect the sharpener with the lid.
