NISOCY 25 Pack Double Sided Black Silver Square Foil Balloons - Balloon Arch Kit for New Year, Birthday, Wedding, Graduation, Anniversary Party Decorations

This 25-piece set of square foil balloons from NISOCY features a double-sided design: black on one side and silver on the other. Each balloon measures 19 by 19 inches before inflation and shrinks to about 13 by 13 inches when fully inflated. Made from durable mylar, these balloons hold their shape longer than latex and are less prone to popping. Perfect for New Year, birthdays, weddings, graduations, anniversaries, or any party backdrop.

What Are the Dimensions and Materials of These Balloons?

Each balloon is made of high-quality mylar foil, giving a metallic sheen that reflects light beautifully. Before inflation, the squares are 19 x 19 inches; after inflating to the recommended 85% capacity, they become approximately 13 x 13 inches. The double-sided coloring means you can flip them to alternate black and silver for dynamic patterns.

How to Set Up the Double Sided Balloon Wall Backdrop?

Assembly is simple: tie the balloons together at their ribbons to form arches, tunnels, or a flat backdrop. You can combine them with latex balloons, flowers, or ribbons for extra flair. For inflation, use the included straw to gently open the valve if it's sealed tight. An electric air pump makes the job faster. Important: do not inflate beyond 85% of the full size to prevent bursting. The balloons work well both indoors and outdoors, staying shiny under party lights.

Frequently Asked Questions

Why does the color look different from the product images?

Metallic surfaces reflect light, so brightness and angle can change the appearance. In bright light, colors may seem more intense; in dim settings, they soften. This is normal for foil balloons.

Why is it hard to inflate the square balloon?

The opening might be tightly sealed during packaging. Use the straw to pry it open gently before attaching your pump. Also, manual inflation takes longer due to the size – an electric pump is recommended.

Why does my balloon leak air after inflation?

Press the inflation opening firmly to seal it. Over-inflation can stretch the opening and cause leaks. If problems continue, contact support. Avoid inflating beyond 85%.

Can these balloons be reused?

Yes. After your event, gently deflate each balloon by inserting a straw into the valve. Store them flat in a cool, dry place. They can be reinflated for future parties, reducing waste.

Where Can You Use These Balloons?

These square balloons are versatile for any celebration: New Year, birthday, wedding, graduation, anniversary, engagement, prom, or themed parties like Christmas and Halloween. Create a stunning photo backdrop, a balloon arch entrance, or a ceiling decoration. The double-sided design lets you mix black and silver easily. Their metallic finish catches light, adding a elegant touch to indoor or outdoor setups.
