Above par.highly recommend
My students love the addition of the cork massage balls at my studio.
The bigger ones are great for shoulder blades, pecs, glutes, etc. The smaller one is great for head and temporal muscles.
They worked much better than the balls that I had been using previously. However I was surprised when they arrived at the weight of them. The cork blocks that I have previously ordered from half moon seem to be heavier so I was expecting the balls to be the same density and to have more weight. they are quite light so for some things that I want my student to do with them they will still role around to much. All in all a good product.
So hard I can hardly stand them. ..
