Acne carabiner. It originally came with a key ring, but the key ring has been lost, so this is just the carabiner. There are some minor scratches, but no major damage. I'm offering it at a low price. Size: Inner diameter approx. 27mm, Outer diameter approx. 38mm I will conduct transactions with the first person to purchase, regardless of the circumstances. If you're interested, please consider purchasing it as soon as possible. This item has been handled by a person once, so please refrain from purchasing if you are overly concerned about minor details.
