Add a festive and fun-filled glam to your party with our Balloonify Black Mylar Letter E Balloon. With its letter E-shaped design, this party balloon goes perfectly with our Balloonify letter and number balloons. This letter balloon is made from mylar and is moistureproof to ensure that its float life won't be affected by humidity. The self-sealing design of this reusable birthday balloon avoids air leakage for longer performance. This mylar balloon can be inflated using a hand pump rather than inflating it yourself for ease. With a classic metallic black finish, this custom balloon provides a chic look to your events. Equipped with hanging loops, this metallic balloon can be hung on any surface. This foil balloon measures 16 inches in length when filled 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.
