Giant Foil Letter Balloons Size & Capacity: These giant foil letter balloons are approximately 34" when inflated. The helium capacity is approximately 2 to 2.2 cubic feet per foil letter balloon. The valve built into the neck of the balloon is self-sealing allowing the foil letter balloon to be re-inflated to extend its float-time. Once filled simply attached curling ribbon or nylon line. Helium-filled giant foil letter balloons have an average good float-time of 5-7 days but may last longer depending on conditions. Once inflated, avoid exposure to extreme temperatures. In cold air, the helium balloon will deflate slightly, exposure to warm air will restore proper inflation. Excessive heat could cause the balloon to burst.
Inflation Advice: Always under-inflate foil balloons if you do not have an auto-shutoff valve on your helium cylinder. This will reduce the burst risk and allow for helium expansion in warmer environments. Do not fill the foil balloon tight and leave crinkles along the balloon seam.
Caution: Do not release helium-filled balloons outdoors or near power lines. This balloon may conduct electricity. Misuse can cause injury. Dispose of properly. Helium gas should never be inhaled.
