Sending a square envelope for cards or letters correctly

If you prefer standard formats such as C6 envelopes or DL envelopes If you want to avoid looking too ordinary, the square format is the right choice. The envelopes, measuring 15.5x15.5 cm and 13x13 cm, can be franked with a standard stamp. Most of our square envelopes in this section have a pointed flap closure. This is located on the back and can be easily closed by tucking it in for personal delivery. For postal delivery, we recommend using the wet adhesive gumming. Lightly moistening the adhesive surface activates the glue and seals the square envelope securely and reliably for transport.
