Harlequin highball glasses, very thin glass. I thought possibly Lindshammar, but haven't been able to find this combination of colours - the red and blue are particularly distinctive. Others are purple/amethyst, smoke, sage green, and teal. They feel Scandinavian to me, but I'm open to other ideas.
Slightly concave bases which result in a small "hump" in the bottom of each glass. Flat cut rims, which feel a little rough to the touch on a couple of glasses. A few random bubbles and striations in the glass.
Approx. 15.5cm high x 6cm diameter, weights vary 84-108g.
They feel so fragile, I can't believe they've survived three moves unscathed.
Thank you for looking.
