When do you need windowed envelopes?
These C6/5 envelopes with a window on the left are ideal for business correspondence where you want the address to show automatically. You mainly use them for sending letters, invoices or other documents where the address on the letter must be legible through the window. This saves time, as you don't need to stick on address labels or write addresses by hand.

Why the C6/5 format with the window on the left?
The C6/5 format of 114 × 229 mm is perfect for folded A4 documents and fits in most letterboxes. The window is positioned on the left, which matches many standard letter templates where the address field sits on the left. This format offers enough room for official documents while remaining compact enough for efficient dispatch.

What does the nassklebung with ISK mean?
These envelopes have a nassklebung, which means you need to moisten them with water to seal them. ISK stands for innenliegende Seitenklappen - these are the side flaps on the inside, which give a neater finish without visible glue edges on the outside. The round mouth flap gives a professional appearance.

Practical benefits of the bulk pack
With 1000 pieces in one pack, you're well stocked for a long time and benefit from a competitive price per piece. The envelopes have sicherheitsschlitze (security slits) that prevent anyone from reading the contents without opening the envelope. The 80 g/m² offset white paper offers solid quality suitable for professional correspondence.
