● Wrist circumference (actual size): Approximately 19cm (using silicone rubber). 21 silver obsidian beads, 1 charoite bead, and 8 natural crystal beads. ● If requested, I can adjust the size, from 16cm to 19cm. ● Silver obsidian: Approximately 8mm in diameter. ● Charoite: Approximately 8mm in diameter. ● Color: Refer to the photos. ● Since they are natural materials, there may be extremely minor natural imperfections. Please be aware of this. ● The main effect of charoite is "healing." It has a strong spiritual healing effect and can also be described as an energy detoxification effect.
