LUXPaperA4 Invitation Envelopes for 4 x 6 Cards in 80 lb. Navy, Printable Envelopes for Invitations, 50 Pack, Envelope Size 4 1/4 x 6 1/4 (Blue)

We were looking for a nice envelope to use with a "save-the-date" card. The card is 4x6 and fit's perfectly in these envelopes. We like that the envelopes feel elegant, making them worthy of our announcement. They are dark blue so plan on using either a white pen or mailing label for addressing.

These envelopes are wonderful. They are sturdy and great quality. The peel and stick seal works great as well. I used these for sending out save the dates and got several compliments on the quality and the gorgeous navy color. I will definitely be purchasing envelopes from this brand again! I highly recommend buying these, you won't be disappointed!

These envelopes are great quality, however since they are so dark, it is very hard to see any writing on them. I ended up printing "to" and "from" labels on white paper and gluing them to the envelopes. If you do this, use a strong glue; I used a glue stick and several labels came off in the mail and were returned to me. They are self sealing so you do not need to lick them to close them, which is nice. You just peel off a strip of paper to reveal the (very, very) sticky glue.

I bought these to use for my son's birthday invitations. Rather than shelling out tons of cash for fancy invites, I designed my own and had them printed as 4x6 photos for super cheap. I ordered these and they fit perfectly. Plus, no licking dozens and dozens of envelopes since these are peel and stick. The navy color is a nice bold, deep blue and perfect for my little guy's party.

The Astrobrite paper of these envelopes is vivid and easy to write on. Even though the colors are intense, whatever you write or print on them is clearly legible.
