Using these balloons is super easy. If you want them to float, use a helium tank to fill them up. Just make sure to inflate them close to the start of your event so they float for as long as possible - about 10 hours. If you don't need them to float, you can use a regular air pump or just blow them up by mouth. They'll last between 5 - 7 days when filled with air. When handling the balloons, be careful not to let them rub against sharp objects as latex can easily pop. Store any unused balloons in a cool, dry place away from direct sunlight to keep them in good condition.
