The standard envelope is highly versatile. You can use it to send out your own 4” x 6” invitations, greeting cards, photos, announcements, and other event stationery. These inexpensive envelopes are made of quality, bright white paper that pairs nicely with a wide range of color schemes. The flap is straight edged and gummed. When moistened it will create a permanent seal to keep the contents inside secure for mailing. The envelope is a cheap priced option for mailing your custom stationery and sharing handmade cards, family photos, holiday greeting cards, or party invites with family and friends.
