They are shaped like a long, thin cylinder, and when you shake them like maracas, the beads inside produce a pleasant sound.
They don't make the same rattling sound as regular maracas, but rather the sound of larger beads rolling around inside the tube, which you can feel in your hand.
They also come in a set of two, so you can use them like a clave by hitting the sticks together.
They come in two colors: blue and red.
Their shape is appealing to children, so they could be used in a variety of ways, such as placing them in hospital waiting rooms or as part of music therapy in nursing homes.
