Hinge Cap for R's KOSO Bottle

The perfect addition to top off my RS Koso routine

RS Koso has become part of my daily ritual and had many positive impacts on my health. I feel like my digestion is easier, my overall immune system is stronger and I think this all relates to improved gut health. The Hinge Cap prevents any drips of this tonic around the top of the bottle, any stickiness build up is gone. The cap is easy to use and transfer to the next bottle when needed.

Hinged bottle top

Thank you for the hinged bottle cap. It keeps the bottle top sticky free and pours perfectly. I will be ordering another as we use both regular and less sugar RS KOSO.

Helpful Cap

I appreciate receiving the cap as a bonus but it seems like it should come with the bottle/s. Also, it would be nice if it had a slight directional pour. As far as KOSO itself, I love it! Reminds me a little of homemade Plum wine my Japanese Great Aunt used to make. I bought both the sweet and less sweet versions and enjoy them both. I’ll drink the sweet if I’m just grabbing a glass and like a small teaspoon in the less sweet version as a change (and when I’m being more sugar conscious). Thanks for making a great product to help us with our health.
