The feminine noun 'szklanka' (glass) declines regularly (genitive plural 'szklanek'). It refers specifically to a cylindrical drinking glass (typically without a stem or handle, used for water, juice, or tea). Do not confuse it with 'szkło' (the material glass), 'kieliszek' (stemmed wine glass or shot glass), or 'szyba' (windowpane).
