Mechanical pencil is a new pencil with a spring. By pressing the back cover, pencil lead can extend a fixed length from the front end to write fonts with the same thickness. It is very convenient because it doesn't need to be sharpened like a traditional pencil.
There is no applicable age in mechanical pencil, but mechanical pencil is generally not recommended for children who are too young. Considering the safety and physical development of children, it is recommended to use mechanical pencil at least after the third grade.
Why not recommend mechanical pencil to primary school students?

There are many detachable spare parts in mechanical pencil. Many children were curious and took mechanical pencil apart. If they eat spare parts by mistake, it may be dangerous; In addition, mechanical pencil's refill is very thin. If a child fights with mechanical pencil, it is easy to hurt others.
2. mechanical pencil will distract children.

There are 0.5 and 0.7 mechanical pencil, but they are thinner than traditional pencils. Many pupils learn to write for the first time, usually with great effort, so mechanical pencil is easy to break.
