Kamen Rider Build children's muffler! It features Build's face as a key point and looks very cool. It's a rare design that is no longer sold. Made of boa material, it's warm, and it's the type that you can insert and wrap, so it seems easy for children to use. There are a few pills on the felt part (Build's eyes), but there are no stains, and I think it's clean. Thank you very much! (^人^) Kamen Rider Build Rare Scarce Hero Muffler Boa Kids
