The "Rock" espresso cups in Concrete... Sizes cups: Holds: 80ml. hight:6cm. diameter: 6cm. A wonderful and basic shape that loves to be hold by your hands for that little delightful sip of strong cafe... The "Rock" collection is made in honour of the beauty of pure stoneware clays that are available or that we home mix. in this case less is more ;) Also important with this design is respect for the material used and use it wisely, recycle and ofcource the pureness it is made with.
