Can I express the thermos bottle? How to send?

Hot water bottles can be sent by courier or mail:

1. Wash the thermos bottle with warm water of 50-60 degrees to prevent the injected hot water from exploding due to excessive temperature difference.

2. Tighten the back cover by hand to prevent the back cover at the bottom of the bottle from loosening, causing the bottle liner to slide and break.

3. Fill the inside of the thermos bottle with sponge, leaving no gaps.

4. Prepare a large cardboard box with a layer of foam board inside, and wrap it outside the English thermos bottle with shock-proof fat-blind foam without covering it.
