MATERIAL UPGRADE - The Halloween balloons are different from the traditional rubber balloon, it is made of A-grade aluminum foil material and will not break or leak easily. It will be automatically sealed after filling, and the balloon will float after adding helium and can be reused after deflating. HOW TO INFLATE - Halloween balloons are very light in weight. You simply use a straw or air pump to fill the balloon to 90% air or helium to prevent popping and leaking during inflation. After inflation, the balloon will automatically seal and look full and delicate. You can place the Halloween balloons anywhere you like, or tie a ribbon to make the balloon float and start an unforgettable party! HALLOWEEN DECORATION - Halloween balloons are a wonderful addition to your Halloween decorations, adding an extra spooky touch that will impress your guests, and the versatility allows you to be creative and match your theme perfectly. You can use Halloween balloons to create haunted house entrances, spooky balloon bundles, table centerpieces, Halloween party games, and as a photo backdrop to capture those precious memories and save them in an album.
