Buffalo checked Gingham Mugs' set of 4 different colors

These vintage coffee cups do not look used (my opinion only). There are no signs of usage or repeated washing as would be seen on vintage cups like these. My guess is 70s, but without any markings, it's hard to say. I couldn't find any mugs like these on Google search. There are signs of vintage like the quality (see photo of speck in the mug. It is a sign of not mixing the sand thoroughly and seen in a couple of spots. These mugs are absolutely gorgeous regardless, and without finding any others exactly like them, they would make a flawless gift for that hard to buy for person in your life! Perfect for everyday use. premium materials and excellent craftsmanship ensure long-lasting durability.
