OK I have no experience sending stuff through a courier service. Right now I have a pair of faulty earphones which I bought for RM300, and I have to send it back to China for repairs/replacement. The thing is small and weighs very little, probably around 20g. I dont mind if it takes a while to reach china, anything less than 20 working days is fine. I think a bubble-padded envelope should be enough (the couriers will provide this right?). Which courier best fits my needs? I don't want to spend a fortune sending it back there. I checked Pos Laju and the cheapest rate I got was RM28 (excluding surcharges) for international document. Do earphones enclosed in a padded envelope fall under documents or parcel?

Thanks.
