How it compares on the envelopes & mailing shelf

Across the 49 rated envelopes & mailing products we track, the middle of the pack sits at 4.6 out of 5. This one scores 4.6. That's mid-table. Star ratings won't separate this from its neighbours, so the decision comes down to pack size, price per unit and whether the specifics below suit you.

Behind that score sit 27,186 ratings, against a shelf median of 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. Cheap with a middling rating is a fair trade if the specifics suit you, and it is the usual reason to pick something at this end of the shelf.
