Establish the perfect look for your event with our Balloonify Rose Gold Mylar Number 0 Balloon. To create lovely messages, combine this number 0-shaped party balloon with our other Balloonify number and letter balloons. This number balloon is made of mylar and is moistureproof, so humidity will not reduce its float life. With minimal wear and tear, this durable birthday balloon is ideal for reusing. This mylar balloon has a self-sealing valve that keeps the air inside without leaking, allowing the balloon to maintain its shape. To speed up the inflating process, fill this mylar balloon using an automatic or manual pump. This custom balloon has a rose gold finish that adds a royal touch to your party. The built-in hanging loops on this graduation balloon allows it to be hung from surfaces. Measuring 40 inches in length, this foil balloon can be inflated with air or helium. To reuse this balloon, gently deflate, properly store, and carefully reinflate without overfilling. Shipped deflated in a 1 count box. This party balloon can be easily inflated with the included straw, providing you with full control to help eliminate the risk of over-inflation. Electric air balloon pump (SKU: RWP1061) is available and sold separately.
