are 15yr old fireworks just as safe as the newer fireworks. i need 2 know very very very soon.. thanx

If you stored them right, they will work just fine.

I lit off some 20 yr old morning glories my friend had in proper storage, and they worked just fine.

thnx an ya, my house is prety dry, they were in my closet.

You're in Airzona, so you'll have better luck than someone in Florida. I'd say they will work properly and safely, but take extra caution anyway.

Old firecrackers sure seem to be a hell of a lot louder than newer ones. Not sure why.
