Envelope folder Donau Teczka kopertowa DONAU with snap closure, PP, DL size, 180 µm, yellow

Donau Teczka kopertowa DONAU with snap closure is a DL-size envelope folder made from durable polypropylene (PP) with a 180 µm material thickness. The bright yellow color makes this envelope easy to spot in filing cabinets, mail batches or when carrying documents between meetings. It is designed to store and transport letters, invoices and single-sheet documents securely while protecting them from moisture and light wear.

The 180 µm thickness delivers extra rigidity compared with standard thin sleeves, helping prevent bending and creasing of contents. The DL format fits standard envelopes and paper sizes folded to DL, enabling straightforward mailing and storage.
