This is a belt loop key holder made of cowhide, stingray (ray) leather, and brass hardware. The manufacturer is "S'FACTORY," a leather craft workshop in Nerima, known for its commitment to genuine leather and processing techniques. They produce in small quantities and offer rare leather products, including one-of-a-kind items, making it a brand where you might not be able to get a piece once it's sold. The base is cowhide, and the gray, bumpy area in the center is stingray (ray) leather, with the surface shaved flat for a glassy feel. The hardware is made of brass and features S'FACTORY's emblem and a carefully considered design. The two key holder parts can be easily separated with a single fingertip. However, they won't come off easily during normal use (don't worry). As shown in the photos, it has a button closure that easily attaches to your belt. Recommended for those who want to own something unique and different. First, you won't find anyone else with the same item. And the feel of genuine leather provides a sense of satisfaction every time you touch it. Size: Leather part is approximately 9cm long and 3.5cm wide (compare with a cigarette). Weight: It has some weight due to the genuine leather and brass construction. It has a strong presence, so you'd have to be very careless to lose it.
