This 12-piece iridescent foil balloon set from Biapian includes three sizes—10, 15, and 22 inches—in a 4D clear ball shape. The holographic, light-reflecting surface creates a shimmering effect perfect for mermaid-themed parties, weddings, baby showers, and more. Each balloon comes with a straw and a 10-meter ribbon for easy hanging. Note: these balloons are not helium-compatible; they are designed for air inflation and can be hung upside down for a floating look.

What Sizes Are Included in This Balloon Set?

The pack contains 12 balloons in three graduated sizes: five 10-inch balloons, four 15-inch balloons, and three 22-inch balloons. This range lets you build layered displays—use the larger ones as focal points and smaller ones to fill gaps. The 22-inch balloons measure about 56 cm across, the 15-inch about 38 cm, and the 10-inch about 25 cm.

How to Inflate These Balloons

Inflate with air using the included straw—no helium needed. For the best shape, fill each balloon to about 90% capacity, then slowly add more air until it reaches 95% full. This prevents overstretching and keeps the balloon plump and round. The self-sealing valve locks the air in, so no tying is required.

Design and Material Highlights

Made from premium aluminum foil, these balloons feature a 4D design that gives them a fuller, more dimensional look compared to standard round balloons. The iridescent coating shifts colors as it catches light, creating a rainbow-like effect that works beautifully with pastel or bright party themes. The surface is smooth and shiny, and the self-sealing valve helps maintain inflation over time.

Versatile Party Decor Options

These balloons suit a wide range of celebrations: mermaid or sea-themed parties, girls' birthdays, princess parties, graduations, proms, weddings, anniversaries, Valentine's Day, Christmas, and New Year's Eve. Use them to build arches, backdrop walls, or table centerpieces. Their iridescent sheen adds a magical, festive touch to any setup.

Important Usage Notes

Because of the iridescent coating, these balloons cannot float with helium—they are intended for air only. For a floating appearance, hang them upside down from the ceiling. The surface reflects light differently from various angles, so colors may shift depending on your lighting. Choking hazard: keep uninflated balloons away from children under 8.
