If you want to fill the ballons with gas or helium, we recommend to seal them using with Hi-Float. Advantage: the balloons are more durable with the Hi-Float sealing. Additionally, the floating period of latex ballons is extended.
Aside from Hi-Float itself, you will also need the Hi-Float pump to seal balloons using the gel. The pump is re-usable, but not included in the refill set.
Contents: 710 ml, sufficient for approximately 150 round balloons size B95 / 11".
