RoyalMail is a British state-run postal system, which means the same as China Post in China, but it is also an independent enterprise. The British Royal family owns part of the shares, so its name is Royal. Its history can be traced back to 15 16, and it undertakes major postal services in Britain and internationally, including letters, parcels, express delivery services, postal business halls, savings, logistics and business etiquette services. Royalmail is slow to become famous, especially in economy, and it is the cheapest one. Generally, it will be faster to use specialdelivery, and even be tracked, but that will be expensive, so it is estimated that the seller will not default.
