Mothered advised to not use dIssapearing ink iirc, because it is a roll of the dice. The ink can be made visible again, and then you are royaly fucked because it shows intent to fraud. Its too big of a irregularity to be ignored for a delivery service repeatedly. It draws attention because packages don't lose their labels. Mailfraud is no joke in some countries. With FTID you can at least plead some ignorance and the delivery service will likely not be bothered as much.

I dont want to cast shade on your accomplishments tho. Congrats
