【Inflation and Deflation】
You can use a straw or a pump to inflate from the inflation port (please note: do not insert the straw too deep, otherwise it may leak). When deflating, insert a straw into the balloon, and then press the balloon to slowly expel the gas, which is convenient for storage and can be used repeatedly.

【Notes】
●Please pinch the inflation inlet twice gently to prevent the air leakage.
●Please do not inflate the balloon to full.
●Please deflate the balloon a little bit in summer or when the temperature rises due to the thermal expansion and contraction of the gas.
●Please inflate the balloon on the day of use as helium or hydrogen can float for 6-14 hours.

【About helium and hydrogen】 ️
The balloons can float in the air when inflated with hydrogen or helium. The helium is an inert gas so we highly recommend that you use helium as it’s much safer than hydrogen, which will explode in the air when there is fire. If you have to use hydrogen, please stay away
