We keep Double Dragon 60 Mixed Size Self-Seal Mailer Bags 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: See the latest price and availability on Amazon. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.3 out of 5 on Amazon from 14,740 ratings. Where that leaves it next to the rest of the shelf is set out below.
Shelf price range checked · details
We track 49 rated envelopes & mailing products, and the middle of that pack scores 4.6 out of 5. This one is on 4.3. That lands in the bottom quarter. Nothing alarming on its own, though at this money you can find better-rated neighbours, so there should be a particular reason for choosing it.
That score rests on 14,740 ratings. The median for this shelf is 2,495. That's a deep enough base for the score to be stable, and it is the reason we rank on volume as well as stars.
Price-wise it falls in the bottom third of a shelf that stretches £1.20 to £29.99, with £7.99 in the middle. Buying at the cheap end is fine as long as the rating stands up. Here it does not quite, so check what has been cut before assuming the saving is free.
