Set of 4 soup/cereal bowls in vibrant cobalt blue and white. Each bowl measures 5.375" in diameter and stands 2.25" tall. There are no tags or backstamps visible to verify the manufacturer or country of manufacture. I am guessing that these are the Otagiri-OMC brand based on my research of similar items listed on Ebay.
At the time of this listing I also have a set of 4 matching smaller bowls in this same pattern, suitable for desserts/rice bowls. Check out my store to take a look at these as well. I am happy to combine shipping on multiple orders whenever it can be done safely so as not to damage the merchandise.
