This is a Phiten titanium chain necklace, 60cm long. Included are the box and warranty. I purchased it online, and although I have the warranty, there's nothing specifically written on it. I used it when I first bought it, but I purchased something else and haven't used this one in a while, so I'm putting it up for sale. It has almost no scratches and I think it's like new. Since it's 60cm long, it should be fine even for work where you wear a suit, as it will be hidden by your dress shirt. Thank you. Phiten bonus included.
