Do you notice that the color pencils of Korea are special?
We do not need to use a pencil sharpener to sharpen the pencil when we use it until flat. There is a string to open up the next layer of the lead of the pencil. Isn't it amazing?
Do you see the mini circles of the pencil (photo above)? That's the signals of the life of the pencil. I think it is also a way of decorating the pencil.
