This is a set of Mammut carabiners and belay devices. The product names, as researched by AI, are: Mammut Smart HMS Mammut Smart 2.0 I'm not sure if this is accurate, but the items for sale are those in the photos. Purchased about 4 years ago, used for a few months on top rope at an indoor gym, but I stopped top roping, so the usage count is low. I haven't used them on mountains or outdoor rocks, so there are no noticeable scratches, but there are minor scratches. The carabiner has some paint wear where the rope makes contact. The gate and lock function without any problems. Immediate purchase is possible.
