This is a wingless bird from the Thug Club. The original price was over 100,000 yen. This is a guaranteed authentic item purchased at the "why are you here" store (receipt image in the 5th photo). It has been worn by Sanwon, Ilio, and Anshin of Alpha Drive One. It has also been worn by Niki of ENHYPEN and Ren Hiramoto. It is currently sold out everywhere and the price has gone up considerably. It can be worn over zip-up hoodies and regular hoodies, so it's highly recommended for this winter.
