Back in the days, kings and other high class people used was seals on their documents to protect their important information. With a seal, they prevent people reading the document. Since you have to break the seal, before you could read the document. Nowadays, wax seals are still used by governments. But they are also used by snail mailers! I think it’s a nice way to close the envelop, with using something else then tape. Also, it’s a nice way to decorate the envelope! There is only one danger using these was seals, and that is the fact that you have to use fire to make the seal. Luckily, none of my letter have caught fire while I was making a seal on the envelop!
