Thank you for your review. This issue is discussed in our FAQs page: Please do not be alarmed if you hear a rattling sound inside of some sculptures. That sound is sand which sometimes becomes trapped inside of the sculpture during the casting process. Under the high heat of the furnace, the sand often becomes fused together, creating pebbles. This is common and is a testament to the handmade lost wax casting process and does NOT represent a defect.
We hope you will enjoy this sculpture for many years to come!
