Review on Black Metal Swivel Strong Durable by Jerimiah Augustine

I needed some small swivel carabiners to make a reversible paracord connector for my dog's leash. Many smaller carabiners appear to be jewelry and cheap. These durable carabiners are made from die-cast zinc and are very similar to the larger carabiners on a leash. The photo shows these carabiners compared to a standard carabiner on a line along the ruler.
