Two considerations:

--Mass production. Do you really have a zillion people who can produce hundreds of these balls within one or two weeks? As I recall, the white paper about making them estimated up to 2 hours per ball, unless you can get an efficient assembly process going.

--Shipping. They must be shipped in a container that will protect them from being crushed. If you use foam peanuts for cushioning, the recipient will have to shake foam peanuts out of each ball. However, I don't think they'll need protection from bouncing as much as protection from crushing. Keep in mind when calculating shipping costs that shippers (both USPS and UPS) charge for the size of the box as well as for weight.
