Product description
This pair of giant foil number balloons from OFFCUP brings an immediate focal point to birthday parties and anniversaries, offering clear numeric decoration at a glance. At 40 inches long, the Number 1 and Number 5 design suits milestone celebrations and photo backdrops while being simple to inflate and reuse 🎈.
Key Points
These large foil balloons arrive as a set of two numbers with two plastic straws for inflation, making setup straightforward. The material is glossy aluminium foil with a self-sealing valve to reduce air loss after inflation, which helps them stay inflated longer according to the manufacturer. They include a small hanging hole at the top so they can be suspended on ribbons or attached to stands, and they fold compactly for storage between events.
The balloons are intended for use with helium or air. When filled with helium they float, offering a striking floating display for table arrangements and entrance décor. If air inflation is preferred, they can be mounted on walls or placed on sticks to create a stable photo area. Consider that helium-filled foil balloons may lose buoyancy faster in very warm conditions, according to the manufacturer, so indoor placement on cooler days preserves lift better 🎉.
Technical Specifications
- Name: OFFCUP 40 Inch Number 15 Balloon
- Size: 101 cm (40 inches) per balloon.
- Material: Aluminium foil, non-toxic.
- Quantity: 2 number balloons, plus 2 plastic inflation straws.
- Colour: Blue.
- Valve: Self-sealing automatic valve.
Usage Recommendations
Inflate slowly using the included straw to avoid over-pressurising the seams, and press the self-sealing valve flat after filling to encourage a tight closure. For floating displays use helium tanks rated for party balloons and secure the balloons with a light weight or ribbon to prevent unintended drift. To deflate and store for reuse, insert the straw into the valve and press gently to release the gas, then fold the balloon along its seams and keep it in a cool, dry place.
A minor limitation to note is that these are large single-sided foil shapes, so extreme handling may crease the surface or weaken joins over repeated reuse. If long-duration outdoor use is planned, consider sheltered placement since strong wind or direct sunlight can reduce afloat time.
