I received this as a gift, but I'm selling it because it's not a smart key case. Denim key case. It has one large and one small ring, convenient for attaching keys and connecting parts. It also has a band to store and secure a smart key. *If it's difficult to attach a key directly to the large ring, you can use your own key ring, etc. 〈Size〉 ・Main body: Approximately 10.5cm tall x 7cm wide (when folded) ・Band: Approximately 4.5cm tall x 6cm wide 〈Material〉 Main body: 100% cotton Filling: Front side: Urethane foam Back side: Non-fibrous fiber (paper) 〈Country of origin〉 Made in Japan Original price: 9900 yen #familiar
