These envelopes are very good quality and easy to design with an address. My reply envelopes that came with our invitations did not have an option to make envelopes with our name and address on each reply envelope, so these worked out great. It's hard to find the A1 size and there are several options at your company. Mine turned out great!

I loved them. Very well made, pretty and I love the self-seal tape! I plan to order the same size in other colors too.

I ordered 2 packs of 50 envelopes to self-address for wedding RSVPs. The envelope paper is thicker than your standard white business envelope, but it wasn't bulky. I put this A1 envelope into an A7 Invitation Envelope, along with an RSVP card, Invitation, and Details card and it all fit fine. I didn't need any extra postage, and the A7 envelope didn't look 'stuffed' of bulky. I used gold and silver Sharpies to address this envelope and the metallic markers really popped against the Garnet.

The colour is a really beautiful navy - great for navy colour schemes for weddings and goes great if matching with golds or metallics. The quality is also really high-end. They also shipped really quickly to Canada!
