I bought this here, but it didn't fit my key. I really like it, but I can't use it, so I'm putting it up for sale. The previous seller also said they couldn't attach it to their home key, so I'm listing it as "like new." This is a used item, so please understand. I'm looking for someone who understands and likes Kageyama. Please refer to the photo on the 6th page; it should fit this type of key without any problems. Remove the ball chain, insert the key from the top, and then pull it out from the bottom before reattaching the ball chain. Title...Haikyu!! Haikyu!! / Character Name...Tobio Kageyama
