Essence Cocktail Bowl by Iittala Designed by Alfredo Haberli 2001. The Essence glasses have become a true demonstration of thoughtful design. Standing next to each other they create a wonderful sense of balance. This is due to the fact that the stem and base of each glass are the same size while the tumblers share similar proportions. They are easy to grasp and handle and we suspect they make fine wines even more enjoyable.
