This beautiful set of 4 glasses is from the Kekkerit series designed by Timo Sarapaneva in the 1970s for Iittala, Finland.
These are very large glasses or goblets and would be most suitable for beer or water.
The glasses are heavy, icy looking, sturdy and masculine. They are hollow into the wide stem.
The original iittala transfers are still in place.
The glasses stand 140mm tall and measure 90mm across the rim.
