Triangular postal boxes

(1 product)

Give documents extra protection in the post with our triangular postal boxes

Triangular postal boxes offer extra protection to products in the post and make your packaging stand out from the crowd. The unique shape also stops your products from rolling away during packing. Made from tough, crush-resistant board, these exceptionally strong boxes are ideal for rolled documents or long cylindrical products.

Quick to assemble and fold, our triangular boxes come with a simple peel and seal-strip that keeps the contents free from dust and dirt. Choose postal boxes in lengths up to 1100mm and get all the triangular postal boxes you need delivered flat packed the next day.


Pack as close as possible to reduce the weight and volume of your parcel.
