Completely smooth silicone surface allows for even spreading, and edges are tapered to a sharp point to scrape sides clean. The flexible, curved edge scrapes bowls clean while the nylon core creates rigidity for thick batters and doughs. The soft-touch silicone will not scratch cast iron or nonstick pans. Silicone spatula is heat-resistant up to 600 degrees Fahrenheit. Dishwasher safe.
