The A4 TOUGH box — designed for schools, offices & busy craft rooms

  • Heavy duty construction: The A4 TOUGH box is made from high-impact polypropylene — a significantly more robust grade of the same material used in our standard A4 box. Built for environments where standard polypropylene would be subject to heavier-than-normal handling — classrooms, workshops, healthcare settings, and busy craft rooms.
  • Same precise A4 fit: Internal dimensions of 304 x 216 x 55mm hold a full ream of 500 sheets of 80gsm A4 paper — identical to the standard A4 box. The same precise fit, the same clean base and drop-on lid design, just in a significantly more impact-resistant material.
  • Archival safe: Made from acid-free polypropylene — safe for long-term storage of documents, printed media, artwork, and paper supplies.
  • Opaque white: The opaque finish means contents are not visible from outside — useful in classroom and office environments where a clean, uniform appearance across multiple boxes is preferred.
  • Made in Britain: Manufactured from recyclable polypropylene at our factory in Sunbury-on-Thames. Available in packs of 5, 10, and 40.

A4 TOUGH box — frequently asked questions

What are the dimensions of the WestonBoxes A4 TOUGH box and what does it hold?

The A4 TOUGH box measures 312 x 225 x 57mm externally and 304 x 216 x 55mm internally — identical dimensions to the standard WestonBoxes A4 box. It holds a full ream of 500 sheets of 80gsm A4 paper. The internal dimensions are sized to hold A4 paper flat without movement, with enough clearance to prevent corner-curl.

What is the difference between the TOUGH box and the standard A4 box?

The dimensions and design are identical — the difference is the material.

Choose the TOUGH box for demanding environments; choose the standard box where colour options or transparency matter.

Is the WestonBoxes A4 TOUGH box acid-free?

The A4 TOUGH box is made from high-impact PP5 polypropylene — a chemically inert, recyclable plastic that is acid-free, moisture-resistant, and significantly more robust than standard polypropylene. Opaque white finish. Wipes clean easily.
