Help students improve respiration and lip rounding with Pop Toobs! Students blow through one or two Toobs connected together. Keep the Toobs straight or bend them into different shapes. You can also use Pop Toobs for auditory feedback. Speak into one end and bend the other end to the ear. Made in the U.S.A., each 8-inch plastic Toob expands to four times its original length and comes in a variety of colors. Recommended for children 3 years of age and older.
