I haven't worn it much, so it seems to be clean. It's a large size, size 13. Width: Approximately 41cm Length: Approximately 60cm Please note that these measurements are approximate. I would appreciate it if you could understand that this item has been stored at home. There are no smokers in my family. I don't have any pets either. I will use recycled materials for packaging. It's a very easy-to-use and convenient item (*^*)
