25 Thick WALLED SALUTE Firework Tubes Shells 1" x 2-1/2" x 1/8" & 50 Paper plugs

I got these to reload my 37 mm works very well. Would recommend if that's what you are looking for.

...even though the plugs at first seemed too large, in reality they were just the right diameter to make a tight fit. I found that using a deep well socket from a socket wrench set provides the perfect driver for getting the plugs into the tubes without mangling them. The socket should be about 3/32" smaller in diameter than the inside diameter of the plug, which allows the lip of the plug to collapse a bit when it's pressed into the tube by the end of the socket. If the plug is slightly cocked to one side after insertion, going back with the socket from the the other side (the inside), straightens the plug right out and allows one to press it evenly to a good seated position in the tube.Hope that that helps someone.These are nice.

I filled these with homemade gunpowder, and the ends always blew out even with a generous helping of hot glue and Duct Tape to reenforce either end. Probably a characteristic of the propellant honestly. Good for the price.

Survives long enough to do it's job, burns when needed.No issues.

All good when contacted were friendly an helpful

Just bear in mind that making, possessing, or using fireworks without a permit is illegal in every state in the union. But if you have a proper permit for where you live, this is good stuff for making fireworks. IF you have the proper permits and skill you probably don't need to buy this in the first place, but just saying it does work. But if you want to make an M-80, these make more of an M-240. But they are exactly as advertised...

Item just as described.
