The set of 6 REGO brown coffee cups are vintage diner and restaurant ware from the 1970s, featuring a solid brown color and made of ceramic(porcelain, stoneware) material. These mugs have a classic diner-style design suitable for breakfast, lunch, dinner, or break time.
The REGO brand signifies authenticity and originality, with a production style of art pottery from China. This unopened set is a collector's item that exudes a nostalgic charm and would be a stylish addition to any kitchen or dining area.
The mug in my hand is not in the set of 6 but it is an identical mug I included the photo for reference.
