This is a Fire King Bubble plate that I purchased at an antique shop while in the US. The color is sapphire blue. It's a large oval size. As it's a large plate, I think it can be used for serving various dishes. ・Size: Approximately 22.5cm (length) x 30cm (width) Approximately 2cm (height) There are no chips or cracks, but there are air bubbles and scratches from the manufacturing process. Please understand that this is a vintage item.
