Thanks for the sizes.
Unfortunately by this big size I can only send to UK and Canada directly via Post office, which is cheapest shipping method for one piece.
For American market, It is over sized by post office.I must find a partner, I will send big quantity by sea freight and partner in change of retail. But by so doing I am afraid that I lose price benefit
Now only question is how big the Canadian market is.
I think I can forget UK.
