The Bitz cup and saucer in black are made of sturdy stoneware. The outside has a reactive, matte glaze that makes each piece unique and contrasts with the cup's bright, colourful inside. Over time, the surface acquires a natural patina, which makes the cup and saucer even more special. Choose from a range of colours on the cup's inside, and feel free to match with other products from the same brand for a uniform table setting. The cup and saucer can withstand temperatures of up to 220°C.
