Tweezers are dull, so you can use a millstone at home or make a new one yourself.

The manufacturing method of tweezers is as follows: 1, roll a square paper roll, then fold it in half and flatten it, so that the sharp points at both ends are reduced;

2. Prepare two toothpicks and stick them on the two ends that have just been cut off;

3. After confirming that the internal bonding is firm, another layer can be used to reinforce the outside.
