Coolrunner 2'' Marble Dark Grey Baoding Balls Chinese Health Stress Relieve Hand Exercise Massage

Thank you, really good quality

amazing ...i use em while listening to music..

They don't have the same depth coloring from the pictures. And one of the balls has a rough spot. I think it's because the white material isn't covered by the resin (I don't know if it's resin but you get the point). Also I can scrape the white stuff by hand. So, I don't know how long that ball gonna stay.

The 2 inch size balls are probably not optimal for me but I can now use them after using smaller balls that helped me with an annoying forearm pain from "tennis elbow" (though I don't play tennis). I think the variety (smaller ball and now these 2 inch balls) will be good for my version of physical therapy for what was the annoying pain in my forearm. I like the sound of the marble rubbing against each other as it is practically like meditation. If it's too difficult at first using this size ball, try ordering a smaller one. Either way, be patient with yourself and things may get better with you as it has with me.

Great, like the fact that it’s real marbel, there’s no chime which is good for when you don’t want to hear the sound, I have a pair that chime that was metal with a casing over it that cracked and exposed the raw metal underneath. This marbel one is great looking and nice size for the medium to large hand size or wider hand size. Great value for your money, therapeutic and relaxing for someone with anxiety or fidgety hands.
