Hey guys I have to send my earphones to China for RMA, and I've put them in a small box (~9cm x 9cm x 5cm), and I want to send it through registered air mail to reduce my costs. I don't mind if it arrives in China after 2 or 3 weeks. But I'm not sure if PosLaju will allow this, and instead might file this under parcel and require me to use courier. So guys, any of you have done something like this before?
