Size: about 47CM X 63CM Material: high-grade aluminum film Style: best-selling style at home and abroad Purpose: Children's toys Design of inflatable port: sealing machine is needed. Warm tip: any balloon, filled with air is not floating, hydrogen or helium gas can float, hydrogen cost is lower, but it is dangerous to encounter fire, when filling hydrogen must be away from the source of fire, helium is inert gas, high cost, but very safe

[Product specification] (Due to different measurement methods, the size will have errors, please refer to the actual product) [special notes] :(1) since the aluminum film balloon has no shrinkage, the aluminum film balloon must be inflated slowly, can be filled to 90% with a pump, and then slowly inflated, so as not to burst. If there are two layers of aluminum film sticky, be sure to stop inflating, gently open the two layers of aluminum film by hand before inflating, otherwise it is easy to damage. (2) Sharp objects, dirty ground, direct sunlight and excessive extrusion are easy to make the sphere damaged and burst (3) Due to the heat expansion and cold contraction of the gas, in winter or when the temperature drops, the aluminum film balloon should be properly inflated; In summer or when the temperature rises, the appropriate to the aluminum balloon deflate, so as not to burst. Helium or hydrogen usually floats for 6-14 hours, so be sure to use a same-day charge (be careful when filling hydrogen!). [Method of use] Aluminum ball breakthrough can only be filled with hydrogen traditional, after the improvement of the technology automatically sealed, the pump can be inflated, so even without hydrogen can still play. [On the failure rate] There is no guarantee for any balloon to be 100%. The failure rate is about 1%-3% [Precautions] Children under 8 years of age should be monitored by adults. Please discard the balloon immediately after it is broken. Try to fill the air with an inflator. Keep the inflated balloon away from your eyes [On air leakage] High temperature, exposure to the sun, friction, beating, extrusion and other factors will lead to air leakage or explosion, and the preservation time depends on the above factors [Warm tips] If it is accidentally broken during use, you can immediately use transparent adhesive paste and replenish the gas, you can rest assured to use
