I would agree that generally my Yahoo.JP purchases have been super clean and often scented of green tea (although I can't tell if it's the original seller or the marshall service that adds the green tea scented wrapping materials. Having said that, many Japanese do smoke (although not necessarily at home) and I have on occasion received items that have a hint of smoke smell. Nothing compared to some of the odors I received before I started asking sellers on Ebay if they were smoke free, but still the occasional Yahoo item does show up with a hint of smoke.
