Handheld cannons are single use cannons prefilled with confetti or streamers. The lowest part contains a pressurized nitrogen cartridge. Easily twist the lowest part of the cannon to the left and the confetti or streamers will be launched into the air. Easy to use, and a great effect. Handheld cannons are available in 28, 50 & 80 cm. Confetti and streamers are flameproof according to NEN-EN-ISO 6941. An official test report is available on request.
