Using these balloons is a breeze! First, you can choose to inflate them with air using a regular balloon pump or with helium if you want them to float. If you use helium, they'll float for around 12 - 18 hours. Just make sure to tie a knot tightly at the end to keep the air or helium inside. When it comes to the party, you can use them for ceiling decorations, hang them up, or simply let them float around to create a festive atmosphere. As for maintenance, once the party is over, you can deflate the balloons and store them flat in a cool, dry place for future use. Since they are biodegradable, you don't have to worry about harming the environment when disposing of them. Just note that this listing only includes the balloons, so you'll need to get other decorations separately if you want a more elaborate setup.
