Thank you for viewing. This is a general-purpose lumbar support belt (supporter). It has mesh fabric in some areas. The material seems to be a mixture of several types, but the ratio is unknown. Please refer to the photos as well. There are no noticeable stains or marks, but since it is a used item, there is a general feeling of use, so it is listed as "slightly scratched or stained." Please consider this before purchasing. Size (measured by the seller) Total length: Approximately 94cm Width: Approximately 17cm
