Ledger deliberately does not use such seals because they are very easy to forge. The Ledger website lists the information with which you can check an original Ledger. There is also a note that they do not put seals on the devices.

What's also not so cool is that official sources of supply are also listed. Digitec is not mentioned by name, so maybe they could hand it in and become an official dealer?
