These are Japanese-made arm covers made of cotton and linen. The reason for the "訳あり" (訳あり means "with a reason" or "imperfect") is minor stains from the manufacturing process. Please understand. Color: Light blue Length: 58cm Thin material. A mix of cotton and linen. The color is light blue. Because it contains linen, it has a smooth and cool feel when worn. It's not a tight fit, but a loose and gentle feel. The upper part doesn't feel constricting, but it doesn't slip down either. Can be used by both men and women. We also have other colors available.
