So I finally took the dive and decided to get custom earphones..

This; however, means that I had to get an ear impression - and I have to ship it to the manufacturer, which in this case is in China (not even sure Mainland or not - where the hell is Zhuhai?  ).

I need help on how to go about doing this.
I'm aware PosLaju has international shipping services offered too, yes? At least, that's what I saw on their website.

Although for the few times I've used PosLaju (both to post and when receiving parcels) they were reliable and I have absolutely no complains, I'm not so sure when it comes to the international scene. I'm probably willing to pay a bit more and have an ease of mind and use other courier services (i.e DHL, FedEx).

But I have no idea how to ship via DHL/FedEx, really.. I know for PosLaju you have to just fill up a form and submit the parcel at a PosLaju counter, but how does it work for FedEx?

Any help/suggestion/advice is greatly appreciated. I'm very excited for my custom built monitors, and I want everything to be as smooth-sailing as possible.
