We were at Hobby Lobby & Cj insisted she buy me some Star Trek magnets. At checkout we found these glasses. Dr. McCoy was missing. As you can see the price was $14.99 but the manager came down to $10 even.
So will I use them? YES
I have a Star Trek coffee cup and saucer like the one used in ST 6, I use it every morning for coffee. I also have the place setting from ST 6. Have not used it yet.
So yes I will use these glasses. I like collecting Star Trek items, but I also like to make use of them on the practical level, after all I can't take them with me if I die.
