It is a ball mainly used for water softening, which has a feature to change hard water to soft water by increasing the cation exchange function.

The black ball, which induces water to be changed to soft water as the ball with a feature makes calcium, magnesium and iron dissolved in water exchange the place with sodium, is largely produced to order as a bath ball, which is formed by adding manganese (Mn) with the major materials loess whose main ingredient is silicon dioxide (SiO2), synthetic zeolite and high-anion tourmaline.

The black ball, which has a high catalyst function and an antimicrobial and sterilizing function is very effective in water softening.
