Balloon Balls - Perfectly round silver foil sphere - 7" size 

Recommended to inflate with a hand pump - these balloons are small and delicate, electric inflators will inflate with too much force. May float with helium - Please be aware when inflating: Do NOT put nozzle too far into the balloon, Do NOT inflate too fast or with too much pressure. When inflated correctly, these balloon balls only have a 1-2% fail rate.
