Take these stones with you easily! Pocket stones are not that big and flat in shape so that you can easily put them in your pocket or other pockets. Because they are flat you can take them comfortably with you during your day.
The stone can be held in the hand and rotated, due to the contact with the skin of the hand, the stone has a calming influence and allows it to exert its forces. Because of the flat shape, they are also comfortable to hold.
