Kastehelmi, the Finnish word for dewdrop, describes the special design of the drinking glasses by Iittala. Inspired by natural beauty, designer Oiva Toikka created the Kastehelmi series in 1964, which with its reflective surface brings out the beauty of glass. The Kastehelmi glasses are available in different sizes and colors, each featuring the distinctive, shimmering texture that captures light and enhances the drinking experience.
