Like the rhythm of a flowing river, the Koski glass tumbler brings a sense of movement and light to your table. Designed by Minna Niskakangas, its textured surface—originally hand-carved into plywood—echoes the rippling patterns of water, making each sip feel effortlessly refreshing.

Mouth-blown from clear glass, these 9 oz. tumblers are lightweight, easy to hold, and perfect for both everyday use and special gatherings. Their organic texture catches the light beautifully, adding a subtle elegance to any setting. Dishwasher-safe for convenience, this set of two is a perfect blend of artistry and practicality—inviting a touch of Nordic nature to every pour.
