Fill them with helium for up to 10 hours of flying time indoors. Fill them with air, and the heavy latex material ensures they’ll remain inflated for days on end. Seal the balloons by knotting the neck, tying them off with ribbon or string, or using one of our plastic balloon clips. Each pack has 10PCS. Balloons arrive uninflated. Children under 8 years can choke or suffocate on uninflated or broken balloons. Adult supervision required.
