Excalibur Fireworks 24 pack artillery kit. The #1 selling artillery shell of all time and considered the best firework artillery shell on the market! I have sold them for years and they are always part of our scripted artillery tubes. There are 24 high quality canisters that break over 250 feet high, and over 200 feet wide. They are unsurpassed by any other consumer artillery shell. Reusable HDPE tubes also come with the product! Do not throw them away!!!
