Funny story:
I helped a friend move over the weekend. At one point, I was bringing boxes out of the truck and into the house and saw FESTOOL on the side. I set the box down and made a mental note to ask him about Festool and if he used them for body work or something (he's an auto mechanic).
Before I saw him again, I remembered that I had given him and his wife a bunch of boxes to help them pack. Awkward conversation averted!
My father-in-law's co-worker sells a lot on eBay and is always looking for boxes and packing material to ship stuff. I've gotten packages via UPS in diaper boxes and in incontinence product boxes.
Hopefully this was a fellow user and not just a red herring! (that said, I don't know that I would ship anything in a Festool box that wasn't a Festool, or even that was a Festool; it's almost like shipping something benign in a box for a high end cellphone...)
