My mother had this obi made. The tag from the kimono shop says "Ro (Summer Weave) Black Formal Obi," but it has both thick and thin sections, and I don't know how it differs from a Nagoya obi. I apologize. It looks unused and has a cool impression, with a modern feel from the diamond-shaped embroidery. - Color: Black - Design: Combination of stripes and patterns - Material: Likely silk Thank you for looking.
