What should I say when selling things at a flea market to attract people to buy them?

It sells postcards of some celebrities, especially postcards and posters of popular young people, which are particularly popular. If everyone comes to buy them, the price can be raised slightly, and they can also sell bottled ones. Paper stars and paper cranes (the mouth of the bottle is wrapped with colored tulle, and some beautifully cut paper pieces are stuffed inside, which sells very well). Girls prefer glass products and toys and dolls. For comics, it is best to sell "Sa Comics" or comics that girls like to read, which are also very popular. For boys, they sell toys and "Ah Shai" comics, and other items such as automatic pens, pencil cases, erasers, and notebooks are a must. It must be new and good-looking, and the rest will depend on the actual situation.
