Corks - 3 small for Internal use

3 small rubber corks for drones. Internal Drone Stoppers are great for shutting off your drone without any visible cork sticking up. They are used to shut off one or more of your drones. This can be when you are breaking in a new reed, getting back into playing shape, or making your set of bagpipes into a practice goose. These drone top stoppers are made of rubber so they will not wear out or break down.
