We keep Double Dragon 50-Pack A6 C6 Manilla Hard Board Backed on our envelopes & mailing shelf alongside 48 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: A6 Manilla Hard Board Backed Envelopes ( 162mm x 114mm), designed to hold A6 documents, certificates, photo prints, invitations, and cards without folding. Constructed with a 120gsm kraft paper front and 1000 micron hard board back, these envelopes prevent bending and creases, keeping your documents, photos. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.7 out of 5 across 570 ratings. How that compares with the rest of the shelf is below.

We track 49 rated envelopes & mailing products, and the middle of that pack scores 4.6 out of 5. This one is on 4.7. That puts it in the top quarter of the shelf. Most things here rate well, so what matters is the gap to the pack rather than the number on its own, and the gap is real.
That score rests on 570 ratings. The median for this shelf is 2,495. That isn't much to go on by the standards of this shelf. Scores this lightly reviewed move easily, so take it as a first impression.
Price-wise it falls in the middle third of a shelf that stretches £1.20 to £29.99, with £7.99 in the middle. That's the middle of the shelf, which is usually the least regretted place to buy from.
