Just like any other sharpener, you simply only need to pop your pencil in the Swäsh Auto-Stop Sharpener and twist it until it's done! The difference is just how safe these sharpeners are. Each canister sharpener features an auto-stop function to prevent leads from oversharpening or breaking, a SuperSafe finger sleeve to protect small and wandering fingers, and a canister that only opens under a child-resistant cover. Unique Auto-Stop SuperSafe pencil sharpeners. Super safe, ultra-tidy, and no more broken leads - these sharpeners have a built-in stopping point to stop pencils from being over-sharpened and snapping. These canister sharpeners are SuperSafe and feature a finger sleeve over the sharpening hole to keep small hands away. The handy canister holds messy sharpenings and only opens at the bottom under a child-resistant locking cover. The robust sharpening blade, hidden inside the canister, will keep sharpening your standard and large-sized pencils for longer. Pack of 12.
