You can make 2pcs 12” balloons out of 1cf, so just multiply the volume by 2 to get estimated count. You can inflate about 550 balloons using the largest tank.

30 days rent free, then it’s $0.3/day ($9/mo).

$150 security deposit refunded when you return the tank. We’ll need a driver license and email to send a contract to upon pick up.

You will also need to have a standard valve if you don’t have one yet, it’s $30 on Amazon
