It says it's a thin shaft, but in reality, the tip is about 12.5mm & is sanded a little thinner just below the ferrule to around 12.2mm, but 6-8" down it is a full shaft. The cue is a monster. The only reason I don't play with it full time is because I don't want to leave a collectable cue in my locker.
