This is a NIKE shoe case. It's an accessory that comes with the purchase of shoes. It's for flat shoes (see photo 6), so sneakers might be difficult. It's also perfect for storing things other than shoes. I will pack it compactly and ship it. Material: Nylon Size: Approximately 45cm x 20cm Thank you for looking. #nike #nylonbag #ナイキ #ナイロンバッグ
