Iittala’s Kartio tumblers are part of the eponymous glassware collection designed by Kaj Franck. Kartio’s unique character comes from the living spirit that Franck has managed to add to the rational, clean geometry. The Kartio collection is a fine example of Finnish glass design: its simple practicality suits the needs of everyday life, and its refined elegance also complements more festive settings. The functional glassware items of the Kartio collection are Nordic design classics that stand the test of time and use. The small tumblers come in a set of six.
