Just the leather.
I only bought this because my gear stick was literally worn out. It was the grey silvered plastic top and bad worn through to white plastic and a piece had broken off which held the button. It all worked but for how long?
I had wanted to change the leather as it looked taffy.
I saw a complete unit with a leathered gear knob but again, leather still tatty.
Just be aware that the new leather will probably be OEM rather than genuine Volvo. You could try and get genuine Volvo.
The concern is that where the gaiter fits around the bottom, it is retained with a plastic ring that runs around the edge. The genuine Volvo part will have corresponding notches cut in the leather to secure it before replacing the plastic clip.
An oem part will be perfectly good leather but you will have to cut your own
Below is probably best.

This has the frame and knotches cut in the leather.
A cheaper and less expensive replacement will need to be cut to a similar pattern.
