Sharpener/eraser combo features an eraser on one side and a sharpener on the other. Sharpener uses German-made blades that are created from high-quality, stainless steel to provide a lasting sharp edge. Easy-to-empty design allows you to quickly separate the sharpener from the canister. Plus, the transparent reservoir keeps the fill level visible to let you easily see when it's time to empty. Canister flips to reveal the single-hole sharpener for safe handling by children.
