Showa Retro Black Nikka Memorial Glasses These are rare items that are difficult to find nowadays. They were stored in a box containing six glasses. I'm not sure if the box is specifically for these glasses. They were forgotten about for 30-40 years? They have been stored as new and unused. They are clean and new without any scratches, but please refrain from purchasing if you are looking for a perfect, brand-new item. They are approximately 6.9 cm square with rounded corners. Height is approximately 7.8 cm.
