The Tuff Scuff Joint Protector is a 2-in-1 tool designed to protect the joint
pin and threads on your cue when it's not being used and has a built in scuffer
to maintain the tip shape. This is a handy and durable tool that's made out of
aluminum with a satin smooth black finish and diamond cuts. Protect your
investment and always keep a scuffer around when you're playing with the Tuff
Scuff Joint Protector Tip Tool. Includes a replaceable scuffer disk that's easy
to install, just peel the back off the self-adhesive disc and place it on the
indented end of the joint protector. This joint protector is available in 5/16 x
18 thread size.

These look nice but do not fit my Meucci Cue which was listed on Meucci's website as a 5/16 x 18 joint. Very dissapointed. Looks like Meucci has the wrong size listed for this cue. These protectors fit my other cues that have the 5/16 x 18 joints so Meucci must be wrong. Gave these 5 stars cause they sure fit nice and look great on my other cues.
