Two in One means you can wear the string on both sides, silver inside or outside.
Please note: Silver products have a limited lifetime, depending on the frequency of movement. Silver products will also naturally discolor over time; this is not a quality defect. This is caused by oxidation of the silver by body temperature and body moisture.
The oxidation does not reduce the bacteriostatic function of silver. Our products do not use Nano-Silver technology.
Always measure the hip circumference without an outerwear.
