I just read through it in the other thread. If it’s such a good fake what’s the chance of USPS spotting it ? How closely do they examine every letter ?
I would not take a chance on it even if it will never get caught. Allowing counterfeits into the system takes revenue away from USPS and will eventually cost you, the taxpayer, more money when they have to be bailed out.
I'm not saying that using one fake roll will do that, but it's a matter of principle, and you'll end up paying for it anyways.
