Has this bottle, which reduces deterioration of soy sauce, started to be sold in the US?

There are major problems with such genuine soy sauce
Deterioration after opening.
It's a pity that even the best soy sauce oxidises and turns sour.
I wish small soy sauce factories would start packing their products in these containers.

Soy sauce tends to deteriorate easily, so it's smart to buy the ones in these containers.
