How can I send a small card without an airplane box?

You can use foam paper, plastic wrap, bubble paper and die.

1, foam paper. Foam paper can cushion the collision of small cards during transportation and play a protective role.

2, plastic wrap. Plastic wrap can be wrapped around the card book in multiple layers to protect it.

3. Bubble film. Bubble film can also play a buffering role, and the bubble film is wound in the same way as plastic wrap.

4, card film sleeve. The card sleeve is an essential artifact to protect the small card, so you must choose a good quality card sleeve.
