Called Kastehelmi (Dewdrop), this collection was design by Oiva Toikka in 1964 and remains a Finnish favorite for its simple elegance. Toikka originally used the bubbled detailing as a method to mask seams in glass, but discovered the design's beauty as an intentional pattern. The texture feels as fantastic as it looks, and the dark grey color elevates its sophistication. These tumblers are dishwasher safe and perfect for juice, milk, or water.
