I love these mugs. I bought the plus-X and tri-X from the 70s version. Those are the films I used the most for many years. These aren’t little tiny mugs. They hold a full 15 to 16 ounces easily. The color is vivid and I overall just really really like looking at them and using them. I do wish the design was put on upside down so I could see the main part of the design when I hold the mug. I guess if you’re left-handed, then it would work out fine. Anyway, you should buy these mugs. They are really awesome.
