Purchased about 20 years ago, I intended to use them and threw away the box, but they've been stored in the cupboard and are completely unused. DONAU CRYSTAL KAMAY Artistic works created by Czech and Slovak artisans, cut glass, set of 5. The delicacy of the cut is amazing. Drinking whiskey on the rocks would probably be delicious. Diameter of the mouth: approximately 8.1 cm, diameter of the base: approximately 6.7 cm, height: approximately 8.7 cm
