You don’t need anything special to buy those packs. The dye is made to appear black and easy to wash off, but it’s actually ultraviolet pigmented and nearly impossible to wash off.
That being said, the vast majority of banks I’m familiar with just have known serial straps and/or GPS tracker straps that activate when lifted out of the drawer. Ink is a bit old-fashioned. Especially with network connected counters, it’s easy enough to flag appearances of know serial bills and most robbers aren’t checking the money for lumps from a GPS pack.
Also you may be missing the point of the dye a bit. It’s so potent that it flags counting machines in small quantities and also cops can identify you as a suspect if it’s unknowingly on your clothes, car seat, bag, etc.
