This is by far the best hand drum we've found. It is colorful and has a great sound. The "swirly" part is actually a durable drumhead that never neads tuning. The child holds the drum in one hand while playing it with the rainbow colored mallet. This drum size is 1" deep by 6" diameter. The price for 1 drum is $15.00, or order 10, and only pay $14.50/each ($145.00 total). Order 20 and only pay $14.00/each ($280.00 total). GROUND SHIPPING IS FREE ON ORDERS OF $100 OR MORE!
