Persuasive Blossoms. Serve a salad or sandwich on the round Oiva plate. A delicate line drawing of hearty flowers by Aino-Maija Metsola decorates Sami Ruotsalainen’s elegantly designed plate. Mix it with other patterns and colors. Oiva's hard porcelain ensures a long lifespan; the glazed color and pattern remains vibrant. It’s dishwasher, microwave and freezer safe. The diameter of this plate is 20 cm.
