I was wondering if there was a good chalk holder that made this easier to deal with.
I haven't ever seen one. As you can see from the cube I'm a swiper & thereby get use of about 75% of the cube.
The last part is just as usable as the beginning but once the cube gets that small I find it awkward to utilize given how I chalk my cue, it feels strange in my hand once it gets that small and gets left for someone else.
