Exercise Balls. Random colours.
The heavier weight may be good for those that want a little deeper massage as they roll these balls around in the hand. To use them very often is to get some health benefits. It will not only be aimed at calming, but there is evidence that the palm is the pathway through electrical synapses to every part of your body as well as your meridians and perhaps your mind.
There are red and green colours and different patterns. We could give them randomly to you but make a preference ion the notes if you wish. Others that pick up could make a choice upon pick up.
