Here's a link to a video of this ocean drum being played on our YouTube channel:

This ocean drum is well constructed of natural wood and goat skin for durability.  It is filled with steel balls which deliver a mesmerising sound of waves crashing against rocks, or slowly lapping at the shoreline, as they roll over the drum.  At 10" in diameter (25cm), it is easily handheld.  Easy and fun to play, very relaxing and unwinding, a perfect gift!
