Silver Number 4 Mylar Balloons
Silver Number Balloon 4
A child's 4th birthday deserves a large balloon to celebrate!
This Silver Number 4 Mylar Balloon can be used alone or paired with another number to help you celebrate a special event in a very big way! Each Silver Number Four Balloon is made of mylar and measures 40 inches tall.
All mylar balloons are helium quality and shipped to you flat without helium. Mylar balloons are easily inflated through the small opening or "tail" on each balloon. These balloons are self-sealing so as soon as you remove the nozzle from the balloon, the balloon will seal. Properly filled mylar balloons are tight with uniform creases along the outer seams. Additionally, a mylar balloon might appear deflated in cold temperatures but will fill out normally when returned to room temperature.
Our 4 inch star balloons require heat sealing to ensure a substantial float time. Heat sealers may be purchased at local discount or craft stores.
Mylar Balloon Fly Times:
- 18 inch mylar balloons will fly for approximately 3 to 5 days when inflated with helium.
- 20 inch star balloons will fly for approximately 3 to 5 days when inflated with helium.
- 36 inch star balloons will fly for approximately 10 days when inflated with helium.
