This is an 86cm silver eyeglass chain and mask chain. Natural stones can be replaced, and those currently listed are also available for replacement. For example, if you want to change the 2mm terahertz to 3mm, or a larger size, or if you want the magnetic beads to be 3mm instead of 2mm, please comment with the desired length in centimeters. Please choose something you are satisfied with. However, these are natural stones, not beads. If you prefer beads, please comment as well, as some people do. The price is based on the cost of the natural stones. Thank you for your understanding. Gold hardware is available. 0.2mm Ope-lon rubber is used instead of wire. How about an anklet and bracelet set? Anklets and bracelets are available with the same design. Please consider them. I will offer a discount. The natural stones used are: Magnetic (with and without) gold. The meaning is health and success. 2mm terahertz. The meaning is health. Hokutolite (green and brown). The meaning is health. The length can also be changed. Please feel free to ask. Thank you for visiting.
