Designed to promote even baking and browning of quick breads and mini cakes, our pans release baked goods in perfect shape and clean up in seconds. They are made in the USA of commercial-grade steel for a lifetime of use. Set of four pans for mini yeast breads, quick breads and pound cakes. Commercial-grade aluminized steel distributes heat quickly and evenly for consistent baking results. The Goldtouch ceramic coating reinforces our pans making them more resistant to abrasion than normal non-stick surfaces and releases food with ease. Won't corrode or rust, even with heavy use. Set of four. Dishwasher safe. Made exclusively for Williams Sonoma in the USA.
