Ronuk Antique 1920’s Handmade Royal Blue Vase 6”

Antique Ronuk royal blue or cobalt vase. These were handmade in the 1920’s and contained cleaning polish. My husband is a potter and says these are hand thrown, not mold made. It’s fascinating how much hand work went into a container for a commercial product! In excellent condition with glaze flaw as shown. Measures approximately 6” tall.
