I purchased this from the official Casetify website at the time (original price: 5700 yen). This is a collaboration product between Casetify and Blackpink ☺︎ It's the same design that Rosé used ☺︎ How about taking it with you to a concert?? I used it a few times and stored it in its box. *There are a few scratches on the corners. Blackpink Jisoo Jennie Rosé Lisa
