Aluminum plate, and it must be seamless aluminum plate, and only seamless aluminum plate can do this. I suffered a loss. Doing a shop is definitely not an expedient measure. What you show your customers must be good. If you take an indecent thing as the front of the store, then customers will think that you are not a mid-to high-end product. Don't try to save money. All you do is buy and sell. A profitable business must have an external image to attract traffic.
