Product Name: 16-inch Color Letter Aluminum Film Balloon 

 Specifications: The height of each letter is about 35 cm, and the width is about 22 cm. The data is provided by the manufacturer. Due to different measurement methods, the actual dimensions may vary. Features:

1, the material is aluminum film, the sphere has a metallic luster, uniform color, and beautiful spherical shape.

2, automatic sealing, inflate the balloon by pressing the air vent flat with your hand, and the glue at the balloon mouth will automatically seal the opening.

 Warm Tip: ① Since aluminum foil balloons have no contractility, it is very important to inflate them slowly. You can use an air pump to inflate them to 80%, and then blow them up with a straw to control the amount of air, to avoid bursting. If there is a situation where the two layers of aluminum foil stick together, you must stop inflating and gently pull the two layers of aluminum foil apart before continuing to inflate, or it is easy to damage the balloon.

Sharp objects, dirty ground, direct sunlight, and excessive compression can easily damage and burst the ball.

③Due to the thermal expansion and contraction of gases, in winter or when the temperature drops, it is necessary to appropriately inflate the aluminum film balloons; in summer or when the temperature rises, it is necessary to appropriately deflate the aluminum film balloons to prevent them from bursting.

Aluminum foil balloons have no stretch, so don't use an electric air pump to inflate them; you can use a manual air pump instead.

⑤ If you accidentally puncture it during use, you can immediately paste it with transparent tape and refill the gas, and it can be used safely.
