• High quality party decoration for themed parties and other events, for both adults and children. Ideal for birthdays, anniversaries, parties, weddings, and all kinds of occasions. • Upon order, you will receive the number you requested in a large size (40 inches/approx. 100 centimeters). • The balloons are easy to fill with the self-sealing valve and will hold their contents for up to two weeks. Please note that the large balloons are suitable for helium and the small ones are for air filling only, as they are too small to float. • The balloon is refillable and reusable (can be refilled multiple times). • The balloons can be easily attached to the four tabs, for example, with strings, threads, ropes, or yarn.
