It has been scientifically proved that copper ions can kill bacteria powerfully, and its natural bacteriostatic effect makes it a healthy material to create a healthier life.

Pure copper bead insole is a good choice for deodorization. Copper beads can also be massaged. Long-term use can strengthen the body, but it hurts at first. Get used to it.
