Ours isn't anything special. Just the colour (we used to have a brown one which was broken a while back) a lovely dark red, 10 cups... Yes, for wee teacup vous with a mouthful lol. The costs £2.50 at the charity shop. Just a slight nick but it's been fixed and no leaks!
However, we make for us two. Boiled water to warm up teapot. Rinse and dry. Add four PG Tips Decaf or Regular pyramid bags. Fill up with freshly boiled water and add a 4 ounces glass of cold milk. Cover teapot and wait 5 minutes minimum. Our cups are 12 ounces. So that's about a full cup and a second one with about a quarter. Enjoy and if you're having decaf. Sleep better lol!
