-Tadaomi Karasuma Model Ring-
A ring designed in the image of Tadaomi Karasuma.
Zigzag lines reminiscent of his hairstyle are engraved on the band, expressing a sharp and powerful impression.
We chose black spinel for the gemstone to symbolize the strictness and reliability of the character. By lining up three stones in the center, the ring gains both presence and a sense of weight.
A truly Karasuma-like ring that exudes mature coolness.
