The sound is undoubtedly one of the most powerful media, as it can take the human spirit in different states of consciousness.
Besides their traditional use for meditation, Tibetan singing bowls are used for deep relaxation and muscle regeneration, to relieve pain in the joints, muscles and shoulders, to ease pain related to sciatica, the digestive system, headaches and migraine or spine injuries, to improve circulation, release tensions or blockages, to open the energy flow, eliminate the toxins from the body. When we relax with the sounds of Tibetan bowls  our concentration improves and our emotional tensions and blockages are eased. The sound with its vibrations can ease mental or emotional pain (low self-esteem, worries, fear, anger, anxiety, depression, insomnia). Tibetan singing bowls and their unique tones are used to stabilise blood pressure, to ease asthma related issues, to renew the functioning of the adrenal gland, to open and stabilise the meridians and to improve the synaptic responses in our brain. They also help children with hyperactive disorders (ADHD) and they stimulate the immune system.
The size of the bowl and the ratio between the metals affect the tone, vibration and quality of sound produced by the bowl. Bowls vary in shapes and looks as they are used for sound therapy in different ways and with different accessories. The most commonly used accessory are the so called “strikers”, which are used to strike to bowls, or wooden mallets which are rotated around the rim of the bowl. 
Diameter of the mouth-rim: 11cm. The bowl's diameter is bigger that it's mouth-rim
