Blue Heart ONE Foil Balloon
This heart-shaped foil balloon features a pastel light blue base with a metallic gold script "One" printed sharply across the centre. Designed to offer a structural alternative to standard round bakes, it provides a clean, thematic visual marker for a baby boy's first birthday celebration. Flat and un-inflated, the foil measures 45 cm (18 inches), filling out to approximately 35 cm (14 inches) once fully inflated with either helium or air. Built with micro-sealed foil walls and an automatic self-sealing internal valve, it minimises helium leakage to maintain its pressure throughout the day. A manual inflation straw is included in the single-pack set.
Our Styling Team's Advice
-
Helium Float Stability: When filling this heart foil with helium, use a standard 35g balloon weight and tie the ribbon short. Because heart foils can sometimes catch drafts and spin, anchoring it close to table level keeps the gold script text facing forward for photos.
-
Wall Display Alternative: If you prefer to save on helium, inflate the balloon with air using the included straw. Apply a small loop of clear balloon tape to the reverse side and stick it directly onto a smooth wall panel or high-chair backdrop.
-
Controlling Creases: Stop inflating as soon as the outer seams look smooth and firm. Over-inflating foil balloons to remove every minor edge crease can strain the micro-seams, especially if room temperatures rise during the party.
