An 18 inch heart shaped balloon inflated with helium. Supplied with a coloured ribbon of your choice, a balloon daisy and a standard weight. In cold air the helium balloon will deflate slightly although exposure to warm air will revive it. Excessive heat may cause the balloon to burst. Caution: Do not release helium-filled balloons outdoors or near power lines. This balloon may conduct electricity. Misuse can cause injury. Dispose of properly. Helium gas should never be inhaled.
