Inflation steps:
1. First find the balloon seal (usually the balloon seal is composed of two layers of plastic paper), and insert the air nozzle between the two layers of paper.
2. Slowly insert the air nozzle into the sealing area 2~3 cm, pinch the plastic paper with your fingers and stick it tightly to the air nozzle (to prevent air leakage), and slowly fill in the air.
3. When the balloon is almost 90% full (the balloon is slightly bulging), reduce the amount of inflation and slow down the inflation speed.
4. Do not charge the gas too full, especially when using it in a high temperature environment. After charging, gently pinch the seal with your fingers.
Deflation steps:
1. Before deflating, please prepare a straw of about 20cm. The diameter can be slightly thicker/the hardness is moderate.
2. Slowly insert one end of the straw into the seal until you can feel the gas spurting out, and gently squeeze the ball to expel the gas.
