Yes they will hold up, if it's wrapped up. But say in 4 months after you dipped and wrapped them up, and you're going to sell it like at a show or to customer, I would open the bag up for inspection to see if it still smells good etc. If not, fluff it up with a blow dryer and spray it with your f/o spray. That's what I did when I used to dip bears and bag them up. I also included a tiny 1oz bottle of f/o with the bears so the customers can freshen them up from time to time. HTH Meg
