You will receive the envelope size that corresponds with your card size. If you would prefer to send a square card in a rectangular envelope that would create 2 inches of empty space in the envelope and make it more likely the envelope will be damaged by the postal service. In addition to this, the post office might flag the mail as “irregular shape” because the envelope isn’t filled all the way. Please contact us with any questions or requests of this sort.
