Why is a sea urchin box offered alongside botanical tableware? Because it is irresistible. And maybe sea urchins are plants in another galaxy. Here on planet Earth, this tiny box is about 1 1/2" high x 2 1/4" wide. Silver wash over copper on pewter. The copper shines through intermittently to capture the intricate surface of a sea urchin at low tide during sunset. Yet another photo courtesy of Elizabeth Albritton.
