Using these balloons is a breeze. First, you can choose to inflate them with either air or helium. If you want them to float, use helium, and they'll stay up for about 12 - 18 hours. When inflating, just be gentle to avoid bursting. These balloons are made of biodegradable latex, so they're environmentally friendly. Remember, this listing only includes the balloons, no other decorations. After the party, you can simply deflate them and keep them flat for future use. Store them in a cool, dry place away from sharp objects to prevent any damage. Enjoy decorating with these lovely pastel pink balloons!
