Using these balloons is super easy. First, if you want them to float, you can fill them with helium using a helium tank. If you don't need them to float, regular air from a balloon pump or by blowing is fine. When filling, be careful not to over - inflate as it might cause the balloon to burst. For events, you can tie them together in clusters and use string to hang them up or place them in balloon weights. After the party, these balloons are biodegradable, so you can dispose of them in an eco - friendly way. Just throw them in your regular compost bin if possible. To keep them in good condition before use, store them in a cool, dry place away from sharp objects that could puncture them.
