This is a "Prologue Tea & Mini Beer Set" consisting of 5 cups & saucers and 5 mini beer glasses, manufactured in the 1970s. Cups: 5 Height: approx. 6.6cm, Diameter: approx. 7.0cm Saucers: 5 Side: approx. 11.8cm Mini Beer Glasses: 5 Height: approx. 10.0cm, Diameter: approx. 5.8cm It appears to be a long-term storage item, basically unused (the HOYA brand stickers have been removed from 3 of the 5 mini beer glasses, so they may have been used or attempted to be used; there were no stickers on the cups from the beginning). However, rust and discoloration are visible on the holder parts of 2 of the mini beer glasses due to humidity (please check the images). Also, due to the structure, some pieces have slight scratches or color transfer on the glass parts caused by the holders. The outer box shows considerable deterioration due to aging, including deformation, stains, and decay.
