I would like to let you know that these items were collected from rural China.     In ancient China, too many old things were left behind in rural areas. Some of them are now dedicated to collecting these old goods.     Therefore, these products are all old, and the color of the product pattern you receive may be slightly different from the picture. But this does not affect its aesthetics and usability. We don't know how old it is.    If you pursue the perfection of the goods, or if you mind them, please do not purchase to avoid unnecessary disputes after receiving the goods.
