The Cose 30mm black plastic D-ring is a durable, crescent-shaped piece with a straight bar, used to attach straps and belts to backpacks and textile accessories. It's a lighter and more economical alternative to metal D-rings. The black finish is discreet and versatile, suitable for backpacks and accessories of any style. It's ideal for lighter items where the weight of metal isn't necessary, while still maintaining good resistance to daily use.
