Honestly, I wouldnt even try to get the smell out. I would return the jellyrolls to the seller and a) ask for my money back or b) ask them to replace the items with ones that dont smell so bad.
eBay has a resolution department if the seller is not willing to cooperate with you.
If you're bent on keeping them, I would seperate and hang outdoors until the smell goes away. But having lived with a smoker in the past, it can take a while.
