WARNING! - This pencil sharpener is not a toy. It is a tool to sharpen woodcased pencils. It is unsuitable for children under age 5 because it has a sharp rotary cutter inside the housing. Oftentimes, very young children are as curious as older, more careful children about how things work. They may figure out how to open this sharpener thereby exposing themselves to injury.
