I believe that they can last quite awhile if stored properly. I can't remember now if you need to store them in baggies in the freezer, or stored in baggies just in a cool, dry, place......ARRG! I just can't remember!
LOL!
I know there are folks on here that can tell you....and me.....how long they can be stored for and how to store them!
Oh, and your Fids are DARLING!!!!!!!
