How to use
Add one packet (30g) of this product to approximately 200L of bathwater, stir well, and then bathe. ◇◇ Experience the benefits of our carefully crafted bathwater ◇◇ Onso is made with an emphasis on creating an authentic, smooth, alkaline bathwater. Therefore, if you use it in water with a high hardness (water containing a lot of calcium and magnesium ions), the bathwater may become cloudy, but this does not affect the quality. This is a phenomenon unique to alkaline bath additives; the white components are calcium carbonate, a known hot spring component.
