A3 envelope brown box?

Here are a few great A3 envelope brown box options I found in the PriceCheck search results for you: The Black A3 Archival Box at R1591 is a high quality choice as it is 50mm deep, providing plenty of space to securely store your A3 documents. For moving or shipping items, the Cardboard Moving Boxes Stock 2 Brown Pack Of 25 available for R126 offers excellent value as a sturdy storage solution. Apologies but I don't see any results specifically for an "A3 envelope brown box". As an experimental assistant, my catalogue access is still limited. Let me know if you would like me to try searching differently or providing any other recommendations.
