This is a spare shaft made for a Tad cue I owned over 10 years ago. The original shaft was already sold with the cue itself. Adam ACSS PRO (piloted) with Tad-compatible copy ring Shaft tip diameter: 13mm Weight: 116g I've checked for warpage, tip scratches, and sound issues, but they are almost unnoticeable, and I feel there are no problems with use. Since this is an old item, there may be small scratches that I have overlooked, but I would like to ask those who understand that this is a used item to purchase it. Thank you for looking.
