Some fast-moving consumer goods chains and well-known department stores have recently launched blind bags for the Spring Festival. Similar to the blind box, the blind bag is a sales model in which merchants randomly place products in opaque paper bags.

Blind bag products include daily necessities, shoes, clothing, books, etc. Because of its unpredictable mystery and low price, it arouses people's curiosity. Some merchants regard blind bag sales as a means of clearing inventory, and even blind bag products have many defective products.
