progressPACK PP V04.07 Premium Dispatch Box Corrugated Cardboard A3 309 x 447 x up to 30 mm Pack of 25 Brown

This item is not corrugated cardboard like started in the description! It is card but it is more flimsy than corrugated. I have had the progressPACK W01.09 before and this was corrugated making it a very ridged and a secure packaging product. This product is not as good, I will have to send my items with foam board for extra strength and protection, something I was hoping to avoid.

Really great quality for calendar shipping
