LEATHER BACKPACKDESCRIPTION JULIUS 20 Spring Summer Collection. This product uses lambskin that has a fine texture that feels like it sticks to your hand. The supple texture fits your body. It is made of durable material, has a large capacity, and is rich in design and functionality. The irregular tucks create a unique drape and three dimensional look, and this design is the brand's specialty. We also have "697BGU1" made from different materials.
