The Helis canister is designed for filling cylinders. With one can, you can fill approximately 10 latex cylinders 5, 4 latex cylinders 10 (with air), 3 latex cylinders 12 (with air), and 1 foil cylinder 19 to the fill height. The number of cylinders may vary depending on factors such as the cylinder manufacturer or weather conditions. 10 and 12-inch cylinders must be partially filled with helium. If you feel they are floating in the air, you should continue to inflate them to full size.

It is important to protect the pressure container from sun and heat above 50 °C. Avoid extreme weather conditions and do not store it near ovens, fireplaces, or anywhere close to fire. Do not puncture or burn it even after use. Keep away from children. The canister contains helium gas, which is not harmful to health or the environment. Helium is weightless, so it may appear as if the can is empty. A damaged package does not guarantee 100% content. Made in Poland.
