Shift knob for the Mazda 3

Mazda CX-9 2012 Grand Touring
What shift knob do you all like for the 2008 Mazda 3 manual shifter? The factory knob came apart. My son wanted a dragon ball Z one from Amazon. It has a thread adapter for three different sizes. That one is coming loose. Need a better quality one. Any advice?

I have quite a few glass-like shift knob castings in various colors and shapes, including spherical two diameters, Miata style, and one other. The threads get tapped directly into the urethane, so they last a long time without any issues. I used to sell them but no longer actively do this. However, these castings are just sitting around so let me know if he would like one that looks like colored glass.
