The 26th Birthday Balloon Circle is a stunning addition to your birthday celebrations! Our foil balloons come in various shapes and colors, providing a premium alternative to traditional latex balloons. While they may be slightly more expensive, their quality and airtight properties make them worth every penny. When inflated with air, these foil balloons can last for several months without noticeable changes. If you choose to inflate it with helium, expect it to float for about 3-7 days, influenced by the surrounding temperature and the balloon's volume. Each balloon features a self-sealing valve that prevents air or helium from escaping after inflation. For optimal inflation, we recommend using a hand pump or a drinking straw. For decoration inspiration, visit our online magazine at www.party-narozeniny.cz. The balloon measures 42 cm in size and has a volume of 13 liters. Please note: all our foil balloons come with a self-sealing valve. Inflate using a hand pump for air inflation. Once inflated, the balloons seal themselves but can be topped up through the sealing valve as needed.
