【Hydrogen Water Vacuum Storage Container】
H2-BAG 500ml (Hydrogen-Infused Liquid Vacuum Storage Container)

This is a portable bottle-type container that allows hydrogen water to be vacuum-stored for one week.
Even with daily dispensing, the dissolved hydrogen concentration in the remaining liquid (when 10% of the full amount remains) can be maintained at 90–100% of the initial concentration.
Even when stored without dispensing for 10 days, a high level of dissolved hydrogen concentration can still be maintained.
