Set of 2 These are "as-is" items with imperfections such as scratches, shape defects, variations in stone color, and irregular shapes from the initial processing. The listing images show examples of scratches and distortions. Please note that we do not upload images showing pale stone colors or stones with unrefined shapes. Please understand that these are "as-is" items before purchasing. The size can be adjusted by removing links. These items use high-purity 99.99% germanium, the same as the regular products. The germanium raw material has been tested by a Japanese public inspection organization, and the result is 100% purity! Important Notes ※ For environmental and cost-saving reasons, the items will be delivered in simple packaging (such as a delivery bag or reused cardboard). Thank you for your understanding.
