Description from Rhythm Tech:

The new Rhythm Tech Pro Tambourine features an over-molded GLS playing edge that provides an incredible feel for players. An innovative comfort handle and more efficient jingle placement actually produce more sound while reducing fatigue and stress on the player’s wrist. The included Pro-mount fits any 3/8″ rod, allowing the Pro-Series Tambourine to be played both on and off mount. Steel jingles and frames coming in Black, White or Red give players the options they need to find the perfect fit for their needs. All of this makes for an extremely versatile tool for drummers, percussionists and singers alike.
