shin-ku BOTTLE

shin-ku BOTTLE is a vacuum container with a check valve, our patented vacuum technology, which can store a variety of liquids in an ultra-high vacuum state. A vacuum can be easily created manually, and air does not flow back into the container when the liquid inside is released.
Therefore, once the container is refilled at hand and a vacuum is created, it can be kept fresh to the last drop. It works well with sake, wine, olive oil, soy sauce, and other alcoholic beverages and foods that are susceptible to oxidation, preventing changes in taste and maintaining freshness and flavor.

Use in Restaurants
