Using these balloons is easy. First, decide if you want to use helium or air. If using helium, make sure you have a helium tank. If using air, you can use a balloon pump or just blow them up by mouth. When inflating, be careful not to over - inflate as this might cause the balloon to burst. These balloons are great for various events like weddings and birthday parties. You can hang them from the ceiling, use them as photo booth props, or just scatter them around the venue. After the event, since they're biodegradable, you can dispose of them in an environmentally friendly way. Store the unused balloons in a cool, dry place away from sharp objects to prevent them from getting punctured.
