Jungle Safari Party Supplies: 60 balloons and 2 ribbons. All our party balloons are shipped in vacuum packaging to prevent them from being oxidized during transportation. Premium Material: Our reusable balloons are made of safe and non-toxic latex. WARNING: Balloons should always be used under adult supervision to ensure children's safety. Easy to Assemble: Blow them up with a mouth, pump or helium. If you want them to float, make sure to fill them with pure helium. Wide Application: Balloon is very suitable for graduation, anniversary, baby shower, jungle animal party, company event, photo shooting, etc. Decorate any indoor or outdoor party as a photo booth background and create lasting memories. Reminder: It's best to do it on the same day, or do it one day in advance for better results. After the balloon is inflated, it will stay for nearly 1-2 weeks, and it still looks good.
