Sowide 7th Mermaid Birthday Decorations — Pink & Blue Balloons Kit for Girls

Create an Enchanted Undersea Celebration

Set the scene with a coordinated mermaid themed kit from Sowide. The star is a giant 40-inch number 7 balloon that draws the eye and becomes a memorable photo backdrop, complemented by two mermaid tail balloons in soft pink and aqua. The color pairing evokes sunlit sea water and playful fairy tales, creating a gentle yet vivid mood for a princess themed party space. The shimmering aluminum foil finish catches light as guests wander through the party, adding a touch of magic to every moment.

The set also includes two sea shell balloons in 20 inches, plus two round mermaid balloons in 18 inches. The four balloon designs work together to echo a sea breeze and shimmering underwater world across the party space. With these shapes, you can weave a cohesive ocean theme from the entrance to the dessert table, and they pair well with other Sowide decorations to extend the look beyond a single centerpiece.

What you get

• 1 x giant 40-inch number 7 balloon
• 2 x mermaid tail balloons in pink and aqua
• 2 x sea shell balloons 20 inch
• 2 x round mermaid balloons 18 inch

Quality and reuse

All balloons are made from aluminum foil, a sturdy and shiny material that holds air or helium for longer and resists bursting. After the celebration you can deflate them for easy storage and reuse on another occasion. This helps you get more value from your party decor and reduces waste without compromising on the wow factor.

Easy to assemble and display

Setup is simple. Open the package, slide the included straw into the mouth of each balloon, and inflate by blowing. The lightweight designs stay afloat with minimal effort, helping you quickly assemble a cheerful undersea display that invites family participation and makes photo moments feel effortless.

Versatile for many occasions

• Mermaid themed birthday parties for girls
• Underwater or ocean themed events
• Baby showers and first birthdays
• Gender reveal and other milestone celebrations

Display ideas and care tips

Combine the pieces into a balloon arch or garland, create a dedicated photo backdrop, or place the giant number 7 as the centerpiece on the dessert table. Consider a simple table runner with coordinating tableware to tie the look together. To extend life, store the deflated pieces flat in a cool, dry place until your next celebration.
