I call these Small Cup/Bowls because I use them as both and can't decide what it's best to call them! They feel lovely in the hand, just the right size to hold.
They can go in the dishwasher, microwave etc, just handle them carefully, as you would if it were a glass. Thrown porcelain with a fine rim, they are strong enough to use for coffee or just your favourite nibbles.
Matt on the outside, clear glazed inside. Approx 7cm high.
