it might not have gotten to the x-ray so soon though:
But when Boodles’ own expert became suspicious the next day, the bag was X-rayed
Boodles’ expert probably was made suspicious by the pebbles…if the Zirconium didn’t trigger those suspicions then the x-rays might not have happened.
Also it’s really funny that they’re so careful, they won’t even OPEN the packages to examine the contents because, wow, that would be a security breach! Meanwhile they have pebbles in the package.
