This type of bottle is good and has its drawbacks. AS is generally used for pots, bottles, bottles, etc. It is safe, strong and resistant to breaks, but its shortcomings are the same as many materials - not high temperature. If you use cold water or warm water, it is harmless to health, but if we use it for hot water, its material will produce substances harmful to human health after being heated.
