Children under the age of three should be used under adult supervision. This item is an inflatable product, and attention should be paid to prevent suffocation accidents. 2. There are generally three options for balloon inflation. Please choose the inflation gas reasonably according to the situation to avoid danger. - Sticky decoration: Air (balloons do not float) is inflated through a straw or pump. - Float effect: Helium (safety gas) Helium is an inert gas, which is relatively safe. - Float Effect: Hydrogen (with a certain degree of danger) is not recommended for use. If used, please note that balloons that burst into the balloon must be kept away from fire. 3. Due to the non contractibility of aluminum film balloons, it is recommended to inflate them to about 80% when using them, Do not contact the balloon with sharp objects, avoid high-temperature storage, sun exposure, and excessive compression, to avoid balloon damage and burst. ADD:The floating effect of balloons is influenced by their size and shape, as well as the purity of helium gas. We cannot guarantee that every balloon can float normally. (circular balloons generally float normally, while irregular balloons are generally difficult to float at normal angles)
