These black and gold party decorations are made from durable materials, ensuring they won't burst easily. They can be inflated with air or helium, and a balloon pump is recommended for quick inflation while keeping the shape intact. The set comes with useful accessories like ribbon, dot glue, and a decorative strip, making it simple to create a beautiful balloon arch. Inflate the balloons, connect them with the strip, and use the ribbon and dot glue to attach them to your party backdrop and fill in any gaps. Perfect for a range of events such as birthdays, graduations, weddings, anniversaries, Halloween, and New Year's celebrations, these decorations add a touch of elegance and luxury to any occasion.
