Enamel Tea Pot
From the revitalized Falconware brand are these enamel teapots in red and grey. The teapot holds just under 1 litre of water making it (depending on your cup of choice) a 2-3 cup pot.
The teapot can be used on a gas hob so is equally useful on a camping trip as it is in the home.
Diameter (at base): 12cm
