After use, the high-quality erasers and sharpeners Sleeve and Sleeve Mini disappear in a red, blue or black cover, which has a triple role: it protects from damage, allows the control of the surface of the eraser (important when we want to put out something carefully) or it works as a container for the collection of ξυσμάτων.
If you want a specific color please let us specify in the comments of your order, otherwise the option plan will be random based on availability
