A 600 ml heat-resistant glass teapot with a removable stainless steel infuser: the leaves brew loose, and lifting the basket out stops the brewing before it turns bitter. Dishwasher and microwave safe.

A 650 ml pot with a stainless steel infuser — low at 9 cm, so it fits on a tray or in a drawer under the worktop. Two or three cups per brew. Thermostatic glass, dishwasher safe.

The smallest pot with an infuser — 600 ml, just 6.5 cm across and 16 cm long. A one-person size: two cups, with nothing left to go cold. Thermal glass, dishwasher safe.

A 950 ml teapot with a bamboo lid — four cups, the size for everyday brewing for two with a refill. The glass takes a flame, so the water boils in the same vessel. Dishwasher safe.

A 1600 ml teapot with a bamboo lid — clear, untinted glass, so you can watch the colour of the brew and catch the moment the tea is ready. The water can be boiled straight on the hob.

The smallest pot with a glass filter — 620 ml, two cups for one person. The filter catches even finely broken leaves, so the brew leaves no sediment in the cup. The water can be boiled on the hob.

A 1200 ml pot with a glass filter — the filter is the same material as the pot, so it picks up no smell and does not alter the taste the way a metal strainer can. 15 cm high. Dishwasher safe.

The largest teapot in the series — 1500 ml, 22 cm long, with a bamboo lid and a filter. Six cups’ worth, so it covers a whole gathering without a second brew. The water can be boiled on the hob.

A 1200 ml teapot in heat-resistant glass with a golden tint and a stainless steel lid — metal does not absorb smells the way wood does, so herbs and tea never carry flavours over. Dishwasher safe.
