About this item

  • More Value for Money: Everyone agrees a set of 100 Kraft Brown A6 Envelopes is great value. But when they’re shrink wrapped and become tattered and lost over time, that value obviously diminishes. But not Sweetzer & Orange A6 Envelopes! These thick self seal invitation envelopes come nestled in their own sturdy box. The ‘value for money’ you expect, is now the value you get – right to the last one!
  • True to Size: When we say A6 plain envelopes for small photos and other things, we mean it. In fact they’re 4.75 x 6.5 inches! So your RSVPs, invitation cards or small greeting cards will fit perfect!
  • Thicker Than Most: You’ve probably seen thinner 120gsm blank envelopes today. Or those ultra-thin ones that seem almost transparent. These, are NOT those. Because you’re using them for some very special cards, documents, photos and invitations you’ll appreciate our matte, thick 150gsm paper stock. They’re non-bleed, so calligraphy pens love them, and you can even pop them in your printer!
  • Just Peel ‘N’ Stick! No one loves paper cuts or eating glue. So these are self seal envelopes! The benefit is obvious. But what you can’t see is how crazy strong these self stick envelopes are. While others open in the post, Sweetzer & Orange Self Adhesive Envelopes stay shut for the whole journey.
  • Made from Recycled Paper: If things like this matter to you also then this set of 100 Kraft Brown A6 Envelopes makes perfect sense. For wedding or baby shower Invites, save the date, greeting cards, Christmas cards, RSVP’s or business envelopes, you can feel good knowing whoever receives it will notice your attention to detail. So why not try them now, risk free with our 12-Month Guarantee.


It seems like the most mundane thing to talk about. But when you consider how many invitations, photos and notes are held as keepsakes inside their envelope-y hug you can begin to imagine how much a nice, heavy weight envelope actually means. And since you’re looking for envelopes, it probably makes sense to make them the nicest possible ones you can. Otherwise, you might as well just stuff them full of thin flimsy invoices, too.

I absolutely love these Sweetzer & Orange A6 Envelopes! The quality is top-notch—the paper is thick and sturdy, making them feel luxurious and durable. They have a smooth texture, which gives them a premium feel, and the color is vibrant and rich.I’ve used these envelopes for sending out invitations and greeting cards, and they never fail to impress. The flap seals securely, and the adhesive is strong, ensuring my mail stays intact during transit. Plus, the A6 size is perfect for cards, notes, and small prints.These envelopes are both functional and stylish, adding a touch of elegance to any correspondence. I highly recommend them! ✉️🌟

This envelope raises the bar for quality. It is perfect for my homemade greeting cards but could easily work for wedding invitations. The self stick adhesive strip works well. Also, paper is thick enough for privacy. I hope it will always be available for future purchases.

My husband uses these to ship his Pokemon cards. They are thick and perfect for the lower value card orders. We will be buying more. So so so so so good

I recently purchased these envelopes. I have used other brands of envelopes in the past. These are by far the best quality envelopes I have used. I will definitely buy these again.

I ordered thank you cards from a photo service with return address envelopes. I used the wrong size and it was too expensive to redo. I planned on inserting a 4” x 6” photo with each thank you card but because I ordered a small size card, that plan wasn’t going to work. I needed envelopes that would fit my small thank you card and 4” x 6” photo. I couldn’t find anything in the stores so once again, Amazon to the rescue. I bought white, A6 4.75” x 6.5” set of 50 self seal. They came on time, even thought I received an email they would be a day late. They came in a nice box in a padded envelope. The quality was very nice. Not flimsy at all. I definitely recommend self seal if an option. Saved time, looks nicer and stuck well. I would purchase from here again.

I got these envelopes when I needed to mail out thank you cards from my wedding. They are very thick which adds to the elegant vibe I was going for. They also have a very good sticker on them so all you need to do is peel away the strip covering it and close the envelope. They do infact stay closed very well. I would buy these again in a heartbeat.

These are EXACTLY what I was looking for. They are the perfect size to fit my hand painted watercolor cards. I split a 9x12 paper into two 4.5x6 cards, and this fits them perfectly. The envelopes are a nice heavy weight that doesn't feel cheap. The adhesive strip is a nice feature.Did I mention how perfect these are? I saw a few reviews that mentioned receiving several crumpled or bent pieces, I did not experience that. My order was packed very well (see photos).Great value for this product!

Used for mail out & wanted something a bit more appealing than basic A4 white envelopes. Looked & felt classier altogether.
