Smoke with clear factory stem wine glass goblet MCM

Distinctive Scandinavian flair abounds in this vintage set of 4 glasses, easily moving from serving wine to water or possibly dessert. The cup is a gray smoke color sitting on a clear, tapered stem each with somewhat of a different look where each factory stem is hand applied. There are stray tendrils of the smoke color in 2 of the stems, pls see pics. The bottom of the cup is unique in that is rather square or flat where the stem attaches giving a midcentury modernist feel. 15cm tall, 9cm across top, 8 cm across base. In as new condition, no makers mark, stray bubbles consistent with hand made pieces, stickers on all 4 pieces.
