Create a picture-perfect background decoration with our Balloonify Rose Gold Mylar Number 3 Balloon. Shaped as the number '3,' this custom balloon is pairable with our other Balloonify number and letter balloons. This party balloon's float life will not be affected by humidity as it has a mylar construction. To be reused for future celebrations, this metallic balloon is built with durable material. This mylar balloon stays inflated by halting accidental air leakage with a self-sealing valve. Instead of blowing it the conventional way, this graduation balloon can be inflated with a hand pump. The rose gold aluminum finish on its exterior gives this number balloon a stylish look. Using the built-in hanging film, this birthday balloon can be hung from walls or ceilings. Measuring 40 inches in length, this moistureproof foil balloon can be inflated with air or helium. To reuse these balloons, gently deflate, properly store, and carefully reinflate without overfilling. Shipped deflated in a 1 count box.
