We want to deliver bottles that are safer and more reliable.
With this in mind, we used an antibacterial finish.
On the stopper, gasket, and exterior of the body with the antibacterial finish, the growth of bacteria is prevented by 99% or more, compared with untreated ones; this means the bottle can be used hygienically at anytime.
