50 x C3 Book WRAP Cardboard Postal Boxes 311x240x50mm - RM Large Letter Sized

It is easy to fold the cardboard flaps at the desired position to accommodate whatever item is being packaged. The quick grab adhesive strip beneath its protective layer provides for a secure sealing alleviating the need for supplemental taping.

Its very thin, almost half the thickness of the usual amazon packaging (picture 1 for comparison). Also the cuts are not cut properly all the way in the middle, you need to use a utility knife, (picture 2 for comparison between the amazon packaging in the back and this packaging in front)I give it 1 star.

I have bought many C3 postal packing boxes, but recently I have found the last 3 suppliers (including these) have stated C3 size - which should easily fit an A4 size book (297mm x 210mm), but the length is 280mm not the 311mm stated on the Amazon order page.For no clear reason, they are still called C3 - which is a specific size, yet they are incorrect. I am a printer and order specific sizes of paper, A4 being one size. These can not be use to send this size of print. Infuriating!I will have to make-do with these, as none of the suppliers have the correct version, but I'm very disappointed that the measurements are all incorrect. Clearly someone is NOT paying attention!!

Solid, strong and easy to use. I'm giving it three stars though because the material is a quite thick, and often makes the package too thick to be large letter size when it shouldn't

Love these! They are a little discoloured in one corner inside but other than that - great!

Great item as described, quick delivery.

This is my third order, first two came with a different brand. But these new ones are terrible! They are falling apart very easily, it is so obvious that they are not suitable for book packaging

Not disappointed in purchase. Good quality, good price.
