This is a Petzl GriGri 2. It's a model compatible with φ8.9mm-11mm ropes. It has been used for many years and has many scratches and scuffs, but it is still perfectly usable. I am selling it because I'm updating my gear. I've attached reflective tape for identification, but I can remove it if requested. It has never been dropped from a height. This is climbing gear that can be a matter of life and death. I was using it without any problems until recently, but please understand the risks of it being a used item before purchasing.
