1-9/16" ID Class C Star Shell Mortar Tubes - Pack of 50 ea.
These tubes were made to be used in consumer fireworks ("Class C") mortar tubes. There's no "standard" consumer mortar tube size. So, be sure and measure the inside diameter (ID) of your tubes to make sure the fit will be right. Keep in mind that finishing these tubes will add a little more to the outside of the tube after taping.
Don't forget your #2 Plastic Mortar Base, which you can find here.
Dimensions: 1-9/16" ID, 1-3/4" OD, 1/16" wall thickness, 3" length
