Hello, the invoice is not typed by machine, which means it is a handwritten invoice, right? In fact, whether it is a handwritten invoice or a machine-printed invoice, as long as it is stamped, it has one function, that is, selling it to you. There are still many handwritten invoices in the market, which is normal and can give you full protection. If the jewelry store doesn't give you any invoices, it will be a big problem. You can complain! I hope I can help you, and I hope to adopt it! !
