Sandalwood Inlaid Chip Tritium Trachea Ring Self-luminous for 25 Years

Inner diameter: 16 18 20 22 mm, four sizes. You must measure the inner diameter of your own old ring before buying. If these four inner diameters don't match your finger, you can also tell me, and I can change it to the inner diameter you need. Sandalwood polished ring, inlaid with mobile phone chips as decoration, inlaid with 2 tritium tubes, can emit light by yourself for 25 years. It is a very cool design. You can choose the color of the tritium tube, blue-blue, blue-green, blue-orange, green-orange, four colors to match.
