These are not actual bowl for dinner! They called singing bowls or bells.. Gosh I really hope you can hear this... The sound that those bowls produced are incredible! Reminds me when I entered Asian Temples and the sound of their bell just make me want to cry... I don t have words to describe the vibration sound touches straight to the bottom of my heart. Crystal Clear crispy decent holy prolonged ring bell... 3 different sized bowl each produce different sounds. Hear them! Feel them! Interact with them! and accept yourself for whoever you are... To use : Place on desk or hard floor (the sounds is more clear and prolonged that way than sit on soft material) Hold only the smallest one on your flat palm or you will eliminate the vibration. Made with Copper . Size large 6 x 3 -1/4 medium 4 1/4 x 2 1/2 small 3 1/2 x 2 . Also a good idea to be used as door bell / Gong
