Innovative design opens to reveal three different pencil sharpeners! The 8mm hole provides a sharp point on any standard size pencil, including graphite. Larger 11mm hole is perfect for pastel, charcoal or beginner pencils. The third 9mm hole is specifically for colored pencils. Transparent shavings canisters show you when they need to be emptied. The two compartments snap closed to measure 2-1/2" high.
