Authentic 18K gold Kihei 2-cut, extremely thin chain ring. Brand new, unused. As I am a jewelry craftsman, I weld (solder) the joints myself. *Ring size can be selected. Please comment with your size when purchasing. Chain rings fit the finger better if they are 1 to 2 sizes larger than regular rings. 2 sizes up is recommended. Multiple purchases with different sizes are also possible. Sizes 20 and above will incur an additional fee of a few hundred yen. Chain width: Approximately 0.7mm Material: K18 Pink Gold This is genuine 18K gold sourced from a chain shop in Okachimachi, Tokyo. It is not plated. It is a domestic product, but I am offering it at a low price. Extremely thin, delicate, and cute. The classic 2-cut Kihei. It has cut surfaces that reflect light and sparkle. I cannot lower the price of this product, but feel free to comment. I also sell chain rings in yellow gold and platinum.
