Comparison with other tourmaline products

Comparison with other tourmaline products Tourmaline generates little amount of negative ions with no external pressure or friction. Many tourmaline products such as bedclothes and underwears generate negative ions only while in use because external force is applied. This bracelet generates negative ions by itself without such force.
