Shuriken clip-on badge. Approximately 6cm. Made of plastic, hollow inside, lightweight and safe. Can also be used as a hair accessory (hair clip). Great as a prop for concept outfits and cosplay of works featuring ninjas, such as Nintama Rantaro and NARUTO. The fourth graders, the idol class of Nintama, also wore capes and shuriken badges! ...How about it? You want one now, don't you? (lol)
