Francois Louis Smart Cap
The Francois Louis Smart Cap will fit on Theo Wanne mouthpieces with the
reed attached. This is great for doublers or those needing a cap while
playing on the bandstand.
The smart cap does not make contact with the ligature. It simply snaps
onto the end of the mouthpiece. The smart cap also includes an
innovative built-in humidifier to prevent the reed from drying out.
