Here's what other sites are saying:
This baked enamelware cup is rugged and easy to clean--great for cabin or camp.
Introduce some rustic, old-fashioned charm into your kitchen or campsite with the Red Enamelware Cups from GSI Outdoors. Heavy-gauge steel construction with stainless rim boasts classic speckled-enamel finish and has been kiln-hardened twice to withstand scratches and chipping, ensuring years of use. Three-ply construction maximizes heat distribution. Available: 12-oz. Red Cup, 24-oz. Red Cup. Color: Red.
Maybe it's not technically-advanced. Maybe it looks like it was delivered via Conestoga wagon. But that's just it. If enamelware can survive the ardors of the Oregon Trail, we're sure that it can handle anything the modern world dish out.
