but some seller here post item like screen protector using pos express
maybe cos its thin and lightweight like paper, or they dont tell the pos express people

anyway, one potential buyer want to buy my usb wireless
but he insist on pos express...zzzz
I never use posexpress before, only postlaju

yes, screen protector very light..cant tell the difference..
but usb got physical shape, so they will return back to u..or worst..it will gone to nowhere knows..
if ur buyer insist, then let him bear the risk.
