Put it in a clean and dry locker. Don't put it directly, especially in wet places, which is easy to nourish bacteria.

If you don't mind, it's OK to send me.

If you are afraid of waste, send it to someone who needs it. If you are not afraid of waste, you can disassemble it for other purposes, such as water absorption, or directly classify and throw it away. It is suggested that if it is still in the shelf life, it can be sent to those who need it.
