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!

All products we have ordered, including the avocado envelopes have been of good quality, arrived quickly, and in good condition!

We used these envelopes for our RSVP cards along with the A7 envelopes of the same color - added some color and pizzazz to our DIY invitations! We used a silver gel pen to write our return address, and it turned out beautifully. Thick, quality envelopes, look great, shipped on time, and no need to lick - what more could you want?

Super great product; sealed great. Custom printing too longer than expected.

Love this product. I purchased these and the A7s and loved them both. The "natural" color was extremely elegant. These came in a very timely manner and were well packaged.

Very happy with the quality of the envelopes. Price was considerably less than if I had purchased from my gift card provider
