How it compares on the envelopes & mailing shelf

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. Top quarter of the shelf. In an aisle where nearly everything rates well, the distance above the middle is the part worth reading, and this one has it.

1,548 people rated it, where the shelf median is 2,495. Enough reviews to trust the direction, not enough to close the question.

The shelf runs from £1.20 to £29.99 and the midpoint is about £7.99. On price, this one is in the middle third. Which is where most sensible buys end up: not the cheapest on the shelf, and not the one you pay a name for.
