What you get is a thoughtfully packaged kit for quick setup. The package includes 1 piece of 40-inch black 3-number balloon, 1 roll of balloon string, and 1 straw for inflation. The premium Mylar foil is durable and capable of holding its shine, and the balloon supports both air and helium for flexible display options. It’s designed for reuse, so you can plan future celebrations with a consistent look.

How to inflate and display

• Locate the self-sealing valve, then inflate slowly with an air pump or straw. Stop around 80% to preserve shape and control.
• If two aluminum foil layers stick together, pause, separate the layers, then resume inflating to avoid damage.
• Use the top holes to thread ribbon and create hanging garlands or standalone displays.

Why consider this numeral balloon for your event? Its oversized presence creates a striking focal point for photos and gatherings, while the neutral black works with many themes and color schemes. You can mix this 3 with other numbers to celebrate milestones such as 10, 15, 20, 23, 25, 30, 40, or 50, adapting the decor to the moment you want to mark.

Care, reuse, and quality: crafted from durable foil Mylar with a premium finish, this balloon is built for repeated use. After deflating, store it flat and away from sharp objects. When you’re ready to reuse, re-inflate and reseal, then fold for future celebrations. If you have questions about setup or quality, our team is happy to assist.
