This is a Mojas-Ojisan Man rubber keyholder produced by Hayato Sano, which was sold at "SWEET CHRISTMAS ～GO GO 2021～". ☆As far as I have checked, this item is not currently listed on Mercari☆ ※ This is a new, unopened item as I purchased it as a spare. I have stored it in a dark place after purchase. As shown in the image, it is unopened, but please understand that there are some creases on the bag before purchasing. I will protect it from water damage and reinforce it with bubble wrap before shipping. M!LK Hayato Sano Daichi Shiozaki Shunta Sono Jotaro Yamanaka Jinto Yoshida
