This Barcelona 2-in-1 small grey teapot and infuser from La Cafetière has the capacity for two cups. Its stainless steel filter has a fine mesh which retains flavour and prevents leaves from leaking into the brew. It holds up to 420ml (0.5 pint, 15 fl oz).
Its high-quality ceramic build and grey/white colour scheme makes it durable both practically and in design. It's also available in a 4-cup model.
