This is the badge of Seshomaru in Inuyasha. Seshomaru is the half-brother of the protagonist Inuyasha. He has powerful demonic powers. He is often depicted with silver hair and golden eyes, and dressed in gorgeous clothes. In this badge, he sits on a crescent moon, showing an elegant and stern temperament.
The main process used for this pin is soft enamel, and the moon is made of gradient transparent paint. Gradient transparent paint can allow two or more colors to transition naturally on the surface of the badge, presenting a color change from dark to light or vice versa, saying goodbye to the monotony of pure colors and making the badge more colorful and smart.
