VTG Japanese Ramekins with Vibrant Floral Butterfly Pattern

🌻🦋 2 matching ramekins measuring 4” in diameter. Dishes feature a repeating mod floral and butterfly pattern. Made in Japan. My guess is 1960s. They remind me of the Royal Crown ‘Paradise’ pattern with a similar motif and colours. Possibly porcelain. In good vintage condition. See photos for minor wear.
