## Before you buy

- The title and detailed size describe 229 × 162 mm, while customer feedback mentions envelopes as 22.5mm wide and slightly narrow. The listing also pairs A5 with C5 terminology. Confirm the usable internal fit for your contents before buying. Customer responses on flexibility are mixed, so the board-backed format should not be assumed to make the whole envelope inflexible or bend-proof. Claims of secure or complete protection are listing claims, not a guarantee of postal handling outcomes.

## A good fit for

- People sending or storing flat A5-sized documents, prints, greeting cards or photographs.
- Offices and small businesses that want self-sealing board-backed mailers in a 50-pack.

## Less suited to

- People whose contents need a precisely confirmed internal width or a flexible padded mailer.
- Items requiring verified waterproof, tamper-proof or guaranteed damage-proof protection.

## Customer feedback

Customer feedback reports positive impressions of quality, versatility, functionality and the adhesive seal, including use for greeting cards and small business items. Experiences with size and flexibility are mixed. For buyers mailing flat prints or documents, the positive seal comments are relevant, while concerns about narrowness make checking the contents against the listed 229 × 162 mm format important. Aggregate ratings lean strongly towards five-star responses, but ratings alone do not explain individual experiences.
- Positive themes: Customers report favourable impressions of quality and versatility.
- Positive themes: Feedback mentions that the adhesive seal sticks well and that the envelopes function well for mailing.
- Mixed feedback: Some customers describe the envelopes as narrow and report mixed experiences with their size.
- Mixed feedback: Feedback on flexibility is mixed, with customers also appreciating that the front does not bend.

## Frequently asked questions

### What size are these envelopes?
The title gives 229 × 162 mm, also described as A5/C5. Customer feedback mentions a 22.5mm width and some find them narrow, so check fit carefully for wider contents.
### How do they close?
The listing specifies a self-seal closure and a 10mm-wide adhesive strip. Peel off the strip and press the flap down.
### Are they suitable for photographs or cards?
The listing positions them for photos, cards and documents, and the board backing is intended to keep flat contents firm. Feedback is mixed on flexibility, so do not treat them as a guarantee against bending.
### What material is listed?
The material is listed as “Fibreboard, Recycled”. The listing does not establish a particular recycled-content percentage.
