Yeah, I don't think you'll smell anything over the peppermint oil. That's strong stuff, and it will certainly at least mask the odor. Be sure and wash the insides of the boxes, too, because every time you put the klickys in there, the plastic box is absorbing the smell. Most ebayers will say on the listing if the items are from a smoke-free home, and that's always a good thing to look for! The tobacco can also yellow the items, besides making them smell.
