Thank you for viewing. I purchased this three years ago and have worn it about three times. There are four buttons on the back. It's a 2-way design, so you can wear it with the buttons in the front. It's a knit, so there's a little wear and tear, but no scratches or stains. I hope to sell it to someone who understands that it is a used item. Thank you. The original price was about 6600 yen.
