What is the name of a card that can be delivered without an envelope?

Cards that can be delivered without envelopes are called postcards. However, this card must be a paper product, not a paper product. China Post cannot accept it as a postcard.

How to use postcards

Postcards can be sent directly to cards with images on them. Images can be photos, paintings or designs, and stamps with full face value must be affixed when posting. There is an image on the front, the postal code, address and name of the recipient are written on the back, and what you want to say to the recipient is written in other areas.

The front of postcards usually features scenic spots, cultural celebrities or New Year greetings, which have many beautiful meanings. Postcards usually appear in sets.

The advantage is that you don't need an envelope, but the disadvantage is that there is little space and no privacy. What is written on the postcard is public and can be seen by others. The content usually does not involve concerns about privacy, so it is called a clear letter. Postcard postage is cheaper than ordinary letters. According to the business description of China Post, ordinary people can print postcards by themselves, but they are not allowed to label China Post. Therefore, many people call postcards issued by post offices postal postcards.
