What is stationery? Where can I get it? Because the company is a new company, these things are not comprehensive. Extra 10 to get the exact answer.

Is to print your company name/company plan on paper. There must be at least one of these two companies, so that people can see what it is. It is usually placed on top of the paper. Or something similar to a watermark, appears as a background on the whole paper. You can design one yourself and then add it to the print format when printing. Or print this company stationery directly, and print it directly on this paper when necessary.
