When mailing, after the post office checks, you seal your box, wrap it with colored wrapping paper (plastic), tie a big knot, and then wrap it with a layer of soft foam paper.
Then when you send it, the post office should put a big box outside, which is a necessary condition to protect your inner packaging from being damaged. You don't need to pack the outer box. Pay at the post office and let them seal the box out at last. Just tell the courier company to label the fragile goods.
Precautions for mailing items:
1. When mailing things, put them in cartons or packages and seal them with tape. If not, for example, the postal service will help customers put it in a box. Of course, there will be an extra charge for boxes. If it is a small piece, the courier will take it back to help the customer pack it.
2. Choose a courier company or postal service. If it is a general online shop to send things, most of them use companies such as Shentong Tongyuan Dayun, and a few are SF Express. Among express delivery, SF Express is the fastest and postal service is slower, but it is suitable for sending large items.
3. The courier will ask for an order. Then weigh it in kilograms. If it is less than 1KG, it is calculated in kilograms.
4. You can choose to pay first, or you can pay by the recipient, express delivery or express delivery. The courier will give the receipt, remember to keep the order well, and in case the goods are damaged, you can use it as proof to ask the courier company for compensation, like the postal service, there will be insurance premium.
