The laws for sling shots.

If I buy a sling shot from this company www.lducompany.com will it be ok to make it into the states? It would be coming from China. I have a friend in Australia who wants me to order one for him because he does not have paypal but I am worried that the slingshot will not make it through Australian customs. This LDU company says that they guarantee delivery to Australia for slingshots but I would like to learn some things so here I am asking. Here is the address to the guaranteed sling shot delivered to Australia for my friend http://www.liangdianup.com/inventory/271201AUS.htm but there is no talk about slingshots shipping to the USA if they are guaranteed or not for delivery.

LOL - I think you are totally wrong in this Forum unless you wanted to record some slingshots sounds and post them in Soundsnap.
