The typical envelopes & mailing product on our shelf scores 4.6 out of 5, measured across 49 rated products. This one comes in at 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 6,260 ratings. The median for this shelf is 2,495. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the top third of a shelf running from £1.20 to £29.99, with the midpoint around £7.99. It costs more than most while rating around the middle, so the extra money needs to be buying something specific: pack size, brand you trust, or a detail below that matters to you.
