Do square envelopes require additional postage?

In the US, square envelopes do tend to require extra postage due to their unusual shape. 

Postage for envelopes is not included in your Papier charge.

If unsure of which stamps you might need for your invitations or save the dates, we recommend reaching out to your local post office to determine which option will be best for your mailing.
