Sea Lion Balloon Stack – Under the Sea Air-Filled Party Display
Our Sea Lion Balloon Stack is a charming, ocean-themed air-filled balloon display designed to bring under-the-sea magic to children’s birthdays and themed celebrations. With its adorable pastel-gradient sea lion foil balloon and a sculpted cluster of blue, aqua, white and bubble-clear latex balloons, this Sea Lion Balloon Stack instantly becomes a joyful centrepiece for any party setup. Whether you’re styling a mermaid birthday, an ocean theme, a nautical baby shower or a summer event, it adds colour, character and instant visual impact.
Because it is completely air-filled, the Sea Lion Balloon Stack lasts significantly longer than traditional helium bouquets and maintains its structure beautifully throughout your celebration. It arrives pre-built and ready to display, making it perfect for cake tables, welcome areas, photo backdrops and party entrance styling. The gentle ocean tones and cute character design make it a favourite choice for younger children and coastal-themed events.
Each display is hand-crafted using premium balloons for rich colour, long-lasting durability and a polished finish. Busy parents and event planners love the convenience — simply place it where you want it and your décor is complete.
Available for Cheltenham Click & Collect, local balloon delivery up to 20 miles, and nationwide shipping (sent deflated), this stack offers flexibility for all party types. Bring underwater fun and adorable character to your celebration with the Sea Lion Balloon Stack — a delightful display guaranteed to make guests smile.
