The color mix of white, purple, and pink decorates the birthday party with fun and unforgettable memories. These decorations help create a magical unicorn party for your sweet girl. 3. Easy to Decorate: All balloons are delivered uninflated. We recommend filling them with helium so the balloons float in the air for a better decoration result. Release the air from the balloons if you are not going to use them for a long time (pump and helium not included). 4. Kid's Favorite: Unicorn balloon decoration is a unique and fantastic ornament for parties including birthdays, baby showers, weddings, bridal showers, and ceremonies. It's simple but lovely to wear the unicorn headband for the girls (age recommendation under 12 years). How could the girls be special without them and take the amazing pictures on their birthday!
