I stored this in a chest of drawers for a long time after using it for a while. There is a tear on the inside. Please check the photos. The outside looks clean. The zipper is YKK. Please understand that this is an old item that has been stored for a long time before purchasing. It will be shipped via Yu-Packet Post, so it will be delivered to your mailbox. Delivery may take some time depending on the region and traffic conditions, so please refrain from purchasing if you are in a hurry.
