Oh come, on! Sure it's bad for the health! But don't you think walking in a big city is even worse? Trust me! It may stink but it's not gonna kill you or your kids! Bad food and car fumes will likely do more harm than nicotine residue. And since we'll all die eventually...
The reason there's a smell is because there's molecules of whatever was burning to produce the smoke embedded in the figure and clothes.
This is NOT brand new, it is considered to be damaged/ used and I, like most serious collectors, wouldn't pay for a new 200 + dollar figure from someone who has either lied or is in denial about the condition of a higher end collectible.
Better or worse than other issues, the fact stands that it is no longer new. Same with items that've been salvaged from a house fire that have a smoke odor.
Why do people mention "from non smoking home" on eBay? Because most folks who want a new item, smoker or not, don't want the new item to have some form of smoke damage. Just because you can't see it doesn't mean it's not considered damage.
If you have to wash it it to be like new, it is not brand new. It contains nicotine /tar residue.....that's not a bonus exclusive accessory.
If everything bought on eBay smelled like smoke, eventually it would become a big deal. Whether one or twenty items from different sellers, it also becomes a hassle if one must wash every single item they received....
It's the principal and the fact of existing damage that's most important here, not how big a deal the opinion of the gravity of the damage.
