Thank you for viewing. This is a set of 13 carabiners, including both titanium and aluminum carabiners. The 7 carabiners in the second photo are titanium, and the 6 in the third photo are aluminum. The key rings attached to the titanium carabiners are also all titanium. One of the three Boundless Voyage screw-type carabiners has been used, so the brass on the screw part is slightly tarnished or has some rust. The other two are unused. The other carabiners are new and unused, and have been stored at home, but I am selling them all together as I declutter.
