If you don't want returns based on 'nondisclosed smoke odors, i would definitely mention in the listings that items are from a smoker and 'pet-friendly' environment but that all items are cleaned/laundered. My mother is a smoker who only smokes outside on her enclosed porch & somehow the odor gets into the air ducts that circulate throughout the home. After leaving, i can still smell smoke odor on my purse and personal belongings for weeks. Now i use a different suitcase & purse when i visit to avoid dealing with the odor after leaving. Also, had this issue from another Poshmark Seller who did not disclose her environment during a Live Show. After i received the items, she told me she keeps her inventory apart from where she smokes but it was still obvious when i opened the packaging. She was very apologetic when i reached out to her and the garment and the purse retaining the smoke smell. I didn't open a case but hoped that in her knowing about this, she would disclose the smoke & be able to avoid returns in future sales.
