I had a really nice folding leather magnetic holder, but it grew legs after a couple of years. A guy around Houston made it. But the replacements he had I did not like the leather at all, so I ended up taking black Gorilla tape and two earth magnets (one on each side of the fold) and making one myself. I used the same Gorilla tape to stick a 1" washer on the bottom of the chalk. Those earth magnets are so strong, you don't need another magnet on the chalk lol -- just a steel washer is fine! These Gorilla tape magnetic chalk holders are lasting at least a year or so -- and no one has walked off with one yet either
