Helibox Helium Balloon Gas Cylinder Disposable Tank, Fills Up To 50 9" Latex Balloons

DISPOSABLE HELIUM BALLOON GAS CYLINDER – Helibox single-use helium balloon gas cylinder, lightweight and portable, ideal for birthdays, weddings, baby showers, corporate events and more. Non-refillable helium tank for convenient home or venue use. FILLS UP TO 50 BALLOONS – Each cylinder contains 0.42 m³ of helium and inflates up to 50 x 9" latex, 25 x 11" latex, 18 x 12" latex or 18–20 x 18" foil balloons (approximate, based on correct inflation). FLOAT TIME & PERFORMANCE – Latex balloons generally float for 6–8 hours, depending on factors such as room temperature and balloon quality. Foil balloons typically stay inflated for 5+ days, making this helium balloon gas cylinder perfect for long-lasting displays. LONGER-LASTING BALLOONS – For extended float time, treat latex balloons with Hi Float (sold separately); this can help them stay afloat up to 25 times longer, ideal for all-day or multi-day events. Any gas leakage or overfilling balloons, even slightly, may reduce the total number of balloons you can inflate.
