Nice Party Accessory: Package of 30 clear heart balloons prefilled with light blue heart confetti, each balloon has undergone rigorous testing to reduce the defect rate as much as possible How to Use: Before inflating the balloon, spray a little water into the balloon, so that the moisture helps the pieces of confetti stick to the balloon, rub the balloon with your hands or hair repeatedly to distribute them uniform inside the balloon About Inflatable: If you fill in helium, please note that the confetti balloon's float time is more short. The reason for the balloon falling is that the helium molecule is too small, not that the balloon is bad. So strongly recommend fill them with air Thicker and More: Clear balloon are made of natural latex material which is long-lasting and Eco-friendly, and prefilled filled with enough confetti (about 1 to 2 grams of confetti) to display better at the party
