This is an SG jumper with Koji Ikeda's name on it. Available for immediate purchase. I bought it at the goods corner during the Wakamatsu Memorial. I am selling it because the size was too big for me. I opened it once to try it on. I tore the side of the plastic bag a little, but the product is still in new condition, only tried on. I would appreciate it if you could purchase it with your understanding. Here are the approximate measurements when laid flat: Length: Approximately 65cm Width: 60cm #BoatRace #KojiIkeda #TakahiroNishiyama #SGJumper #GrandPrixJumper
