USPS First Class Mail International - To Kuching Sarawak

This is a sample USPS First Class Mail International delivery slip. First Class Mail is non-trackable service by USPS but it is also the cheapest you can get for example the fee for this delivery to Kuching Sarawak, (Malaysia) is only $5 USD for an item less than 100gram. The Expected arrival time was about more than 2 weeks to reach my home. In some cases it may takes 3 to 4 weeks due to unforeseen circumstances and delays.
