Hi, I have ordered Kids Air Dry Foam from Alibaba. This clay was about 10kg. I was charged 94 USD to ship from China to Switzerland. I was told by two suppliers of this clay that it is more expensive to ship because it has a special status *chemical. I would like to order more clay but the shipping seems too expensive. If you are able to inform me if there is a cheaper option for me I would be so happy. All the best.
