What should I do if the hat returned by mail order is crushed and deformed?

1. First, prepare a professional hat repairer, as shown below, which can be bought online.

2. Then press the air pump of the hat repairing machine first, and let the repaired model expand into a certain model first.

3. Then put on your hat. Pay attention to the front and back when you put it on. There are hints on the recovery machine. Don't misplace them.

4. Then press the air pump all the time, let the recycling machine fully unfold, and restore the hat.

5. Just wait for the hat to hold up. Don't blow the hat too hard and let it stand for half an hour.
