Review on ✋ Coolrunner 2'' Dark Grey Marble Baoding Balls - Chinese Health Stress Relief Hand Exercise Massage Balls by Alicia Lopez

So they arrived and I was thrilled because I haven't had Baoding balls in years. My 18 month old daughter was immediately interested so I let her hold them as soon as they were taken out of the box. With great delight and to my great dismay, she shoved them together like a dazed methamphetamine rabbit half a dozen times before I could pull them out. I have to tell you, these things are hard marble. Aside from a small chip that I'm pretty sure I can grind away, they're intact and still roll as smoothly as they should. They are great too.
