DL Envelopes

The American DL envelope, also known as the DL envelope, is probably the most common envelope used today. It is a format with which we are already very familiar, as it is the one most companies and even public institutions use to send communications by post - you receive this type of envelope every day in your mailbox at home! In fact, its main use is at a professional and commercial level: invoices, delivery notes, welcome letters to new customers and many other examples are sent in this type of envelope.
