1: Tourmaline ceramic ball is also called electric stone ball or tourmaline mineralized ball. It is a new material which is made of tourmaline, high quality clay and other basic materials.

Product Features: The ceramic ball could adjust the ph value of water, it is helpful for the human body to balance the acid-base level and nutrition. It contains lots of trace elements that our body need such as calcium, magnesium,sodium and potassium, etc. 

2: Maifan stone balls are made of mafan stones with clays by sintering at a certain amount ratio. The ball has stronger adsoption and absorption than the raw maifan ore, it's a non-toxic mineral substance. Soaking the ball into water could increase the biological activity of water, improve the physiological function of body and adjust the pH value of water bi-directionaly.

There are more than 20 various trace elements in maifan stone by testing, more important is the trace elements could promote the activity of enzymes of human body to improve the metabolism of ourselves'. 

3: The negative ion ball has a positive electrode and a negative electrode. Once it contacts water, it can release current in the water instantly. This current is the most suitable for the human body with a current of 0.06mA. When the water comes into contact with the weak current, the hydrogen ions and hydroxide ions in the surrounding water molecules separate. On the one hand, hydrogen ions combine with elctrons to form hydrogen gas, and hydorxide ions combine with surrounding water molecules to form interfacial active substances and produce more than 300 times of negative ions.
