K-packet service has been very restricted to only a few countries. However, they added some additional countries effective this month (August )
So, currently Countries with K-Packet availability are Germany, Russia, Malaysia, USA, Spain, Singapore, UK, Japan, Canada, Thailand, Taiwan, France, Philippines, Hong Kong.
Still I highly recommend to use FedEx since it is faster and safer and price will be more expensive with k-packet if the weight overs 1kg. K-packet is usually good for buying light weight photo cards.
