Steinmetz sobres de envío DIN C4, con ventana, autoadhesivos, 120 g/m², blanco, 250 uds. (4654PR)

For high-volume business correspondence, these Steinmetz C4 envelopes with window eliminate the need for separate address labels—just insert a DIN A4 letter and the recipient's address shows through the bottom-left window. The 80 g/m² paper is opaque enough to keep contents confidential while remaining lightweight for economical postage. A self-adhesive peel-and-seal flap speeds up sealing without moisture, and the straight flap gives a clean, professional look. Pack of 250 keeps your office stocked for weeks.

Highlights

• DIN C4 format (229 x 324 mm) fits A4 documents unfolded
• Window on left, bottom (45 x 90 mm) for standard address alignment
• Self-adhesive peel-and-seal closure—no licking or sponges needed
• 80 g/m² white paper with standard opacity for privacy
• Straight flap for a neat, uniform appearance
• Recyclable paper, suitable for eco-conscious offices

In daily use

Load a stack near your printer and fold letters directly into the envelope—no extra label printing. The window is positioned to match common German and European address block layouts, so invoices, reminders, and official notices go out quickly. The peel-and-seal strip holds firmly even in transit, and the white surface accepts inkjet or laser printing if you need to add a return address or logo. At 250 pieces per box, you'll handle daily mailings without frequent reordering.
