Sizes and Board
How do I know which flute to choose?
The flute types guide explains each one, and our quote always includes a recommendation.
Is double wall always safer?
Not always needed. The single and double wall guide explains when it is worth the extra cost.
Are measurements in the guides inside sizes?
Yes. All box sizes on this site are inside length × width × height in millimetres.
Delivery and Returns
Do the guides recommend particular couriers?
No. They cover packing that works with any UK parcel network.

Fill until the contents stay put when the closed box is shaken. The packing guide explains how.
