This is the Blu-ray of TWICE's 4th World Tour Seoul concert. At the time of release, I accidentally ordered two and thought I had canceled one, but it arrived anyway. I thought, "Oh well," and left it, but I'm moving, so I'm selling it. It's unopened, but I'm selling it for a little less than what I originally paid. I myself was entertained by TWICE, so I would be happy if a fellow fan would buy it. I will be out of the country from February 24th to March 7th, so I will not be able to ship during that time. Thank you for your understanding.
