Use our Balloonify Rose Gold Mylar Letter F Balloon with the same lovely luster again and again. Manufactured using metalized polyester or mylar, this letter balloon is unaffected by moisture, providing more float life. Shaped into the letter F, you'll be able to pair this birthday balloon with other number and letter balloons from the Balloonify collection. The durable mylar construction allows this party balloon to be reused later by inflating and deflating time and time again. Engineered with a self-sealing valve, this mylar balloon can be filled up with air or helium without it leaking, making the whole process easy. To inflate this graduation balloon with ease, you can use a simple hand-held pump to fill up the balloon. Designed with a hanging film, this custom balloon can be hung on walls to set up your celebration background. The shiny rose gold finish of this metallic balloon gives a premium look to your decor. This foil balloon measures 16 inches in length. To reuse these balloons, gently deflate, properly store, and carefully reinflate without overfilling. Shipped deflated in a 1 count box.
