Containing 3 meters of continuous balloon bag material one package will make 5 standard size balloons. If you aren't a fan of the standard size Volcano balloons normally come in simply cut out whatever size you want, you could even just use the whole thing without cutting it to make a single almost 10 foot long balloon, although we definitely do not recommend doing that. This can be used with the STORZ & BICKEL Volcano Solid Valve Set or Easy Valve Balloon With Adapter.
