Feature: Made of high-quality aluminum foil, the sphere has a metallic luster, uniform color and beautiful spherical shape. It can be used repeatedly and it is convenient to inflate and deflate. Don't throw it away once! When inflating the aluminum balloon, you should be free. You can use the pump to fill it up to 90%, and then use straw to blow to control the air volume and avoid bursting. If there are two layers of aluminum foil sticking, you should stop pumping, and gently pull out the two layers of aluminum foil by hand before pumping, otherwise it will be easily damaged. Sharp objects, dirty soil, direct sunlight, and excessive extrusion are easy to damage and crack the ball. Due to thermal expansion and cold gas contraction, the aluminum balloon should be properly inflated in winter or when the temperature drops. Or when the temperature rises in summer, deflate the aluminum balloon properly to avoid breaking.
