congrats on all the birthday ponies! And a really nice seller too!! the smoke may not always come from the seller... all my stuff reeks of smoke because our post lady chain smokes in her car with all our mail :/
I think I know where the smoke came from ! The seller said she didn't know they smelled, but I think the carrier bag that came with them was the origin of the smoke. It reeked of it and the seller probably didn't even notice. Needless to say, I got rid of it as it was making my living room quite unpleasant xD
But I am SO glad that now, after a couple of weeks of being in shelves, the ponies are much better now ! Some don't smell anymore and the ones that do, don't bother at all !
