12 inch black balloons perfect for romantic occasions. The modern design is perfect for any decoration. Thanks to the contrast of colors, these balloons will not go unnoticed!
The balloons are made of latex and can be inflated with either air or helium.
Filled with helium in a closed environment (18° C) float time is approximately 18 hours.
Filled with air in a closed environment (18° C) float time is approximately 20 days.
When inflating latex balloons with air or helium we recommend inflating until the balloon has a tear drop shape. Be careful not to under-inflate (round shape) or over-inflate (pear shaped) for maximum flying times. Latex balloons can be sealed by tying the balloon neck or using one of our balloon closures.
