10-mountain. Purchased new. Used for about 2 months. Tip is Naory S. Joint cap included. There are a few small scratches near the tip. I don't think there are any problems that would hinder use. Total length is about 760mm, a bit long. The diameter of the joint is about 21.3mm. It was very well-received by everyone at the same billiards hall, and several people bought one afterwards. I've gone back to a normal cue, so I'm offering it to someone who will use it.
