Metal Jug / Small Flint Pebbles for Hire
Derbyshire flint pebbles are the only type of stone that will produce the exact sound. The player is expected to either stir the pebbles in the metal jug or pour the contents into a larger metal jug. This jug to jug action should be repeated to provide a flint pebble in a jug sound. One of the drawbacks of the flint is the extreme sharpness of the edges.
