Special reminder: carbonated drinks will feel better than other fruit juice drinks or water. Because there is gas, there is no need to squeeze the bottle, but other drinks may need to squeeze! This is a sealing device! It’s hard to get out of the water without air! For the first time, please note: In case of water leakage, please reinstall the white cushion at the bottle mouth interface or change the surface and press it tightly! There will be water leakage! If it leaks, it will leak naturally, which will affect your feeling of use! No need to be nervous and uneasy（ White cushion is leaking and leaking)
