6 Bohemian crystal liqueur glasses

They are made of bohemian crystal, made in ancient czechoslovakia (the word is engraved on the bottom of each glass but impossible to make it appear in photo). The black lines have slightly pali in a few places, and there is a small shine on one of the glasses (see photos). They are 7cm in diameter and 6cm tall.
