With a look reminiscent of an aged European zinc, these decorative bowls are made to maintain the original finish over time, even when exposed to the elements. Durable as well as beautiful. How brilliant! Fill with natural or ceramic orbs, or display as is for a simply beautiful accent. Decorative interior use only. Do not use with water or plant directly into. Use only with inner pot or liner. Do not use harsh chemicals. -Aged Zinc
