Just like Supergirl, this food jar is not only very pretty, but very strong. The interior and exterior is made stainless steel. The TherMax double wall vacuum insulation provides maximum temperature retention, warm or cold. And it's cool to the touch with warm food. The extra wide mouth is easy to fill, serve from, and clean. It's light, compact, and portable. Holds 10 Oz. (290 ml). Measures about 5" tall, and 3.5" in diameter. Shipping Weight: 3 lbs.
