Very very slow china post air mail small packet from shenzhen china to kuching sarawak malaysia

The slowest delivery time I've experience from China and this is consistently happened when the item is coming from Shenzhen. The item was shipped on the 31 January 2017 from 3 Floor 31 Building, Fuming Industrial Park Pingfu Town Longgang District Shenzhen, Zip 518111. And the item has arrived today on the 28 March 2017 which is about 1 month 28 days that is closed to 2 months time. I understand this is free shipping untracked / unregistered air mail service but the delivery period of 2 month make us thing the item could have been lost or returned to the sender. But in the end its arrived out of the blue at the unexpected moment. Not a good sign for both sellers and receivers of the consignment.






Another item was shipped from the same place and same address on the 21 February 2017 and arrived today on the 28 March 2017. That is approximately 1 month 8 days.
