Aqua and moss green are new colours. Delicate and as fresh as a dewy Scandinavian morning, the Iittala Kastehelmi collection brings a bit of the outdoors into any space. Available in a fresh range of colours inspired by nature, Iittala Kastehelmi is the perfect addition to any home. Kastehelmi tumbler is a new addition to the collection. The surface of the Kastehelmi tumbler seems to sparkle, mimicking the sheen of tiny dew drops that can be seen along stalks of grass and other plants on early summer mornings.
