After use, the high-quality Sleeve and Sleeve Mini erasers disappear into a cover, which has a triple role: it protects against wear, allows for control of the eraser's surface, or functions as a collection container for shavings.

The Sleeve series has already won an award for its ergonomic and user-friendly design:

• Quality eraser in an ergonomic shape for a pleasant, gentle erasing experience
• Attractive protective case for protection against dirt
• Clean erasing, without smudges
• PVC-free
