PostProof Slim A4 Packaging Box

£2.79

Impact resistant slimline A4 packaging box designed for letterheads and other A4 documents.

‘Slim’ boxes are perfect for presenting your print media in a smart and professional way. The smart two-part design means there are no breakable catches or hinges so your box will last longer. At 21mm deep internally, this box will hold up to 150 sheets of A4 paper.


Our PostProof packaging boxes are impact resistant so that your items are protected while in transit. Unlike our storage or presentation boxes, our PostProof range is manufactured in opaque white so the contents cannot be seen. Use this box instead of a padded envelope - simply tape the box closed and post without any additional outer packaging. Ideal for crafters looking to send out greeting cards or scrapbooking products on A4 paper.

Ships as a Royal Mail 'Large Letter' as long as the box and its contents do not weigh more than 750g.
