This is a handmade ring crafted from wood (rosewood) and natural materials (bone). Each piece is made by hand, so no two are exactly alike. It combines rosewood, which was used for the necks of shamisen (a traditional Japanese three-stringed instrument), with old natural materials. Compared to metal rings, it doesn't feel cold and has a gentle touch. Finished with a UV resin coating to enhance water resistance, but it is not completely waterproof. ⸻ Materials ・Wood (rosewood) ・Natural material (bone) ・UV resin finish Size ・Approximately size 23 (Japanese ring size) ※Resizing is not possible. ⸻ Important Notes ・Avoid prolonged contact with water, hot water, or chemicals. ・Due to being handmade and using natural materials, there will be individual differences in color, pattern, and texture. ・Please understand that minor imperfections and variations in appearance are characteristic of the materials. ⸻ Please purchase only if you understand and appreciate handmade items.
