Metallic heart-shaped foil balloons are the cutest decoration for the specialist of occasions. Also available in star-shaped & round. These balloons are self sealing and if you are not using helium we suggest a balloon pump for inflation. WARNING: Balloons are not toys. Children can choke or suffocate on uninflated or broken balloons. Adult supervision is required at all times. Please ensure uninflated balloons are kept away from children, and discard broken balloons immediately.
