I believe everyone knows how brittle pencil lead is. It would be acceptable to carve a bird, a heart, etc. on the pencil lead, but it is eye-opening to have such a wonderful work like the following set of works!
Just like the pencil lead is very strong, the creator only needs to carve as much as he wants without worrying about the edge of the lead breaking.
Friends, please get a pencil and give it a try, and you will understand how difficult it is to complete these works!
