Mettler Office Couvert Fenster links C4

C4 envelopes measuring 229 x 324 mm are ideal for documents in DIN A4 format that should not be folded, such as certificates, diplomas, contracts, and other official documents. Thanks to the recyclable parchment film window, you save an additional step, as the recipient's address, already printed on the document, automatically appears in the window – we call this efficient mail delivery. Additional benefits include laser compatibility (up to 140°C) and a reliable self-adhesive closure that acts like a seal. It's a good idea to keep a stock of these envelopes. The adhesive will remain functional for a long time, as a protective strip effectively prevents drying out. 120 g recycled; wood-free and chlorine-free.
