I'll have to check with my buddies in the warehouse to see what determines which stickers get sent. It may be random, or there may be some rhyme and reason. Not sure. Last I knew, we had Festool stickers, but it's possible we ran out. We do usually include a Tool Nut sticker with most/all orders.
I'll post back when I have some info on Monday.
And, yes, the Festool Fan stickers originate from Germany. Not sure if they are still producing those or not.
