Six gorgeous, premium quality, highball tumblers in smokey crystal glass with heavy bases, dating from the mid-Century period.  To me these look like Moser Czech crystal whisky tumblers but they are unmarked underneath so they must be lookalikes. 
They stand 15.5 cm tall and are 7 cm in diameter.
All six tumblers are in beautiful condition, just one tiny edge chip as shown in last picture, though barely discernible.
