Hi Chantal,
I have listed a couple of trusted wholesale suppliers of NHL products below. Though they are not dropship suppliers, you may contact them directly and enquire if they can dropship for you.
Unfortunately, after searching for hours, we were unable to find any suitable dropshippers of these products.
