Meinl Sonic Energy Suction Holders allow you to move metal singing bowls around freely during sound baths and therapy to focus and massage sound energy on different parts of the body. Before using the suction holders, the singing bowls should be completely free of dust and the suction pads should be slightly moistened. The suction holder should be firmly pressed in the center of the singing bowl and lifted by the solid wood rod. Please check to ensure a secure hold before each use. Do not hold any singing bowl above the face or body. Suitable for Meinl Sonic Energy singing bowls of the Universal, Cosmos, and Energy Therapy series or comparable metal singing bowls up to 650 grams with a plain inner surface. Not recommended for crystal singing bowls.
