Surprise your birthday girl with our Balloonify Rose Gold Mylar Letter Z Balloon. This party balloon, which is shaped like the letter Z, can be paired with our other Balloonify letter and number balloons. Built with moistureproof mylar, this letter balloon is ideal for indoor or outdoor venues. The durability of this custom balloon lets you save it and reuse it later. After being inflated, the self-sealing valve on this birthday balloon shuts off the airflow to preserve the balloon's shape. To make the setup procedure easier, use a hand pump to inflate this metallic balloon. This mylar balloon's rose gold tint gives it a mirror-like shine to reflect the grandeur of your party. You may hang this graduation balloon from walls and ceilings using its built-in hanging loops. Measuring 16 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.
