How do you send confidential documents? Some documents are very confidential, such as blueprints or your employees' salary information, which must not fall into the wrong hands and should also be protected from external influences like rain. The solution? Try this Alba shipping bag made of waterproof nylon, which keeps all contents dry even in heavy rain. A practical zipper also protects your documents from prying eyes. For added security, you can use a cable tie. The nylon bag weighs only 150 g – making it extremely lightweight for mailing. The windows on the front for the address and stamps are ideal.
