Packing Details

 

Firstly we pack the balls in cartons For each cartons, 
Then, we pack our balls using wooden pallet(Plywood) in our export business.
Put the plastic paper in the pallet(waterproof) at first, then put the ball carton into the pallet, and fix the pallet.
The size of wooden pallet: Length: 860mm, Width : 800mm, Height: 750mm
Generally, we offer neutral packing and can according to your requirements.
