This is the carbon fiber version of the 2nd series jump cue researched and developed by ko brotkers. It jumps extremely well. I purchased it new in July. The tip has been changed to a Mezz Tsubasa tip. I am selling it to declutter. I will consider a price reduction for those who purchase immediately. Please only purchase if you understand that this item is stored at home and will be shipped by a non-professional. Thank you. Jump Cue Carbon Shaft #HalloweenOnMercari
