These are replacement sleeves made from washable polyester gauze (Toray Silook). It's difficult to tell from the photo, but they have a stylish woven design of cool-looking plants and flowers. Please see photo 4. There is a stain from a pen (ink) that I accidentally got on it during processing. The location is about 10 cm from the shoulder or the sleeve hem. If you bring it to the shoulder side, it will hardly be visible. Sleeve length: Approximately 57cm Sleeve width: Approximately 33cm Velcro is not attached. You can use them by sewing them directly onto a half-length undergarment with a half-collar or a washable kimono, or since they are 57cm long, you can adjust them by lightly sewing them to match the sleeve length of the kimono. #GansoNeko #GauzeReplacementSleeves #SilookReplacementSleeves
