Premium Cannon Fuse
"Premium Cannon Fuse" is the mainstay of the fireworks industry, used for everything from timing individual shells to entire shows. It is also the fuse used in most hobby cannons. It has a 3mm black powder core and a light lacquer coating.
Be sure to keep it in the bag until ready for use and wrap it with tape or foil once you fuse up your fireworks, as burn speed will be drastically affected by any moisture.
