These are great rattles from one of our former students who is a master professional percussionist and sound healing therapist. He has a keen ear for quality of sound, and each rattle expresses that! You will love them! More rich and full bodied sounds are expressed in the larger rattles, more soft and endearing sounds in the smaller ones. These are natural shells which will, of course be slightly different in color, size, shape, and texture with each shell. Sizes are approximate length. Color of leather may differ.
