Set of 5 vermilion bowls Microwave: Not safe Dishwasher: Safe The black foot of the bowl provides a striking contrast with the vermilion color. These bowls would be perfect for serving clam soup during the March Doll Festival (Hina Matsuri). They are reasonably thick, so they don't get too hot, and unlike porcelain or ceramic, they won't break, making them safe for children. These are used items, so please refrain from purchasing if you are concerned. #Hinamatsuri #Vermilion #Lacquer-style
