Beautify your party hall or event with our Balloonify Gold Mylar Number 3 Balloon. Constructed in the shape of the number '3', pair this custom balloon with our other Balloonify number and letter balloons for your birthday party or anniversary. This party balloon is made of premium mylar, which hinders moisture from affecting its float life. To reuse this long-lasting metallic balloon, deflate it after each event and re-inflate it accordingly. This mylar balloon's self-sealing valve stops sir or helium from leaking out. For a much faster procedure, use a hand pump to inflate this graduation balloon. This number balloon has a golden finish, adding a luxurious vibe to your party hall. Mount this birthday balloon on walls or ceilings with its built-in hanging loops to make your presentations appear nicer. 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.
