For juice, water, milk, and more, iittala Kartio glassware is an enduring essential. The stunning dark pink hue is called "calluna," and is permanently a part of the non-leaded crystal rather than painted on after production, which allows it to glow with such a dreamy depth and never fade no matter how many times it goes through the dishwasher. Designed by Kaj Franck in 1958, iittala Kartio glassware is internationally recognized for its simplicity, beauty and functionality, and is easily combined with other iittala pieces. A stylish and sensible set to own, these timeless tumblers won't live much of their long life behind cupboard doors.
