W E Roberts (Corrugated) Ltd A4 Cardboard Archive Filing Storage Boxes - 15" x 12" x 9"/390mm (L) x 304mm (W) x 238mm (H) (Pack of 20)

Very strong boxes and, once you've worked out what to do, easy to fold and lock the flaps together.

Not as sturdy as I had hoped and could be packed better for transit rather than the cling film used, end ones arrived a bit bashed.

These are very cheap, and just adequate if you are going to put things away somewhere and not expect to handle them much. If these are for documents you will want to access on a regular basis, you will probably do better to spend three times as much and get a more robust version.

Deceptively roomy. One of these will hold the same volume more or less as a lettuce box from a supermarket and is far easier to handle and stack. Good value per box. Not the simplest to fold but the value and effectiveness overrides that.

boxes and excellent size for storage in the loft! Good seller, had a delivery issue and seller did not hesitate to send replacement boxes!

great boxes very sturdy, and always good service.

Not sturdy enough and would not buy again I’m afraid
