These are mismatched fabric slippers made by my grandmother. Material: Jersey knit Please check the images for the size. They can be worn without any problems (*^^*) She started this as a hobby, so there may be some differences in the balance between the left and right, and some imperfections in the sewing and construction. Please check the images before considering a purchase. She says she hopes they can be of use to someone. They have a relaxed fit, and the fabric is made thin.
