Under indoor conditions, the Happy Anniversary Foil Balloon 16 Inches forms a 13.5-inch tall metallic backdrop. Mylar material maintains internal pressure for days. Despite road dust during transport, the gold finish remains reflective for high-contrast photography.
Key Features
- Self-Sealing Valve: One-way internal valve prevents air leakage after inflation. Stays firm without manual tying.
- Built-in Tabs: Reinforced plastic loops sit at the top of each letter. Strings pass through for wall mounting.
- Refillable Foil: Nylon-based material allows deflation and re-inflation via a straw. Folds flat for storage after use.
- Air-Only Capacity: 16-inch volume provides insufficient lift for helium gas. Won't float; mount with tape or string.
Frequently Asked Questions
Do 16 inch foil balloons float with helium?
No, these 16 inch letter balloons lack the internal volume to lift their own foil weight with helium. Use air inflation and the hanging tabs for decor.
How to inflate foil balloons with a straw?
Slide a standard straw into the valve opening and blow until the material feels firm. The self-sealing mechanism prevents air loss once you remove the straw.
