Designed by professor Oiva Toikka, Kastehelmi brings a piece of nature to your table settings. Kastehelmi is 'dewdrop' in Engish. Toikka drew his inspiration for the design from the tiny bead-like dewdrops appearing on leaves after the night dew. The Kastehelmi tumblers are now available in deep and vibrant ultramarine blue. Versatile and tactile, the glasses bring beauty to the everyday. Use the tumblers for water, juice or other cold drinks.
