Envelopes DIN Lang+, Dark Blue Print

A professional look in navy: an envelope sleeve with a flat print in dark blue

Choose a color that exudes confidence and professionalism! A dark blue envelope is certainly not an everyday item and will immediately stand out in a positive way in your recipients’ inboxes. Thanks to their rich color, these high-quality envelopes have a pleasantly understated look without appearing ordinary.

Measuring 229 x 114 mm (DIN Long+), this envelope provides ample space for A4 letters, which are inserted in the traditional folded-in-three format. Since these envelopes have no window, the contents remain completely discreet, which further piques the recipient’s curiosity. The dark blue is printed across the entire surface of the white base paper without any special patterns.
