Drone corks are a valuable practice tool for developing pipers. Beginners often use them to shut off selected drones while focusing on steady blowing, consistent bag pressure, and maintaining a stable tone from one or two drones at a time.
 
Made from durable rubber, these drone corks fit securely into most drone tops and are designed for long-lasting use. If a slightly tighter fit is needed, a small wrap of Teflon tape can easily provide a perfect seal.
 
A simple but essential accessory for practice, setup, and maintenance.
