Lähetyspussi MAILmedia C4 388320 itseliimautuva ikkunalla, valkoinen

MAILmedia C4 mailing bag model 388320 is a white self-adhesive envelope with a transparent address window designed for sending documents and flat items in C4 format.

The construction reduces the need for extra tape or glue and helps keep contents flat and protected from light handling and dust. The product is lightweight for postal cost efficiency while maintaining adequate durability for standard mail and parcel services.

Suitable for

• Sending invoices, contracts and certificates in C4/A4 format
• E‑commerce shipments of documents, brochures and thin catalogues
• Office mailing and interdepartmental document transfers

How to use

Insert the unfolded A4 or C4-size content into the mailing bag with the recipient details aligned to the transparent window.
