Kastehelmi is an iconic glass collection designed by the legendary Oiva Toikka. The groundbreaking raised droplet design was born from Toikka's exploration of ways to hide joint marks in the glass. Kastehelmi features glass bubbles that resemble dewdrops sparkling under the sun. Each piece plays with light in a way that showcases the reflective beauty of the glass. The tumblers are suitable for any cold drinks and ideal for everyday use, both indoor and outdoor. The 4-piece glassware set makes a great gift for those who appreciate timeless beauty.
