Six guiros, each with its own a rubbing-stick. Each guiro is made of recycled plastic and has parallel notches cut in the upper side. It is played by rubbing a stick along the notches to produce a ratchet sound. There are two colors, green and cedar. Change the sound by rubbing the stick over the notches slowly, quickly, in one direction or back and forth. Each guiro measures 7 x 1.5 x 1.5 inches. The rubbing sticks are 7 x 0.75 x 0.75 inches.
