I Is the LIT method based solely dissapering ink , how would this work if I have to use return label Amazon provided me with please sir

As stated above, the label Is printed with the disappearing Ink - with the objective of prematurely fading and rendering It an unidentified consignment.

The problem Is, It may fade to some degree (for example) at the time of storage at the carrier's depot, thereby the label will be reprinted according to the details listed on the manifest.
