Not sure exactly what this is, but I loved the texture of it and the butterfly design. Honestly, at first I thought it was a manta ray in the design but realized it was floral, then I saw the butterfly. It's lovely regardless, perhaps intended to be a sushi plate? I also photographed it on a stand, would look lovely on a shelf (stand not included). It measures approximately 8 inches wide and 6 inches tall. It's rustic if that's a word to describe the way it feels, it's not glazed. There is a tiny white spec near the bottom, I cant feel it so I don't think it's a chip.
No other chips or cracks, it's a mystery.
