I pre-ordered this at the Daikanyama Walk-in Closet. It's a waist bag from the brand's leather collection, EOI (Eagle of Independence). It's waterproof, repelling water and resisting stains, and uses the brand's original high-performance leather. Mister Olive is known for its leather and boasts high-quality, made-in-Japan craftsmanship. It's smaller than the standard model and is perfect for those who carry few items, such as a wallet, phone, and keys.
