The curved bristle head allows full contact inside domed pans to cover more surface for effortless cleaning. The stiff union-bristle blend of natural agave and palm fibers creates a sturdy, scratch-free, long-lasting brush with bristles that dry quickly, won't sour, produce bacteria, and won't bend, break, or matt. Safe for use on seasoned, non-stick, and enameled cooking surfaces, it's ideal for cleaning already-seasoned woks, stir fry pans, cast iron skillets, carbon steel pots, stainless steel pans, griddles, and more.
