## Before you buy

- The listing presents the dimensions as 324 × 229 mm and 32.4L x 22.9W centimetres, which are consistent. Thickness is stated as 90 GSM, a paper weight figure rather than a measurement of envelope depth. The claim of tamper-resistant closure is not accompanied by a security standard or test details.

## A good fit for

- People mailing unfolded A4 documents, certificates, photographs or flat printed materials.
- Offices and small businesses seeking a multipack of self-seal, board-backed envelopes.

## Less suited to

- People who need expandable capacity for bulky or thick contents. The listing describes a flat, board-backed envelope and gives no gusset measurement.

## Customer feedback

Only aggregate rating information is supplied, with no written customer feedback to identify specific strengths, concerns or reasons for ratings. The distribution is mostly five-star but includes three-star and one-star ratings, so experiences appear mixed. These figures cannot establish how well the board backing or seal performs for a particular mailing need.
