Decor balloons are the cornerstone for balloon decorations. Incredible amount of colours, types and sizes. Coordinate with latex balloons to match the theme of your balloon garland, event or photo op. Self-sealing means there is a valve at the bottom of the balloon that when inflated, air or helium does not escape. In that case they can even be reused if needed. Most self-sealing balloons can be inflated with a straw, hand pumps, or electric balloon pumps.
