mod vintage plastic dishes sushi or fondue plates w/ yellow gold enamel made in Japan

60s - 70s vintage plates for fondue or sushi, with divided sections in a very mod design. These are an enamel lacquered plastic, deep mustard gold color, unmarked, made in Japan. I love the gold, so retro!

It's a set of four plates about 9" in diameter. They have some scratches and scuffs though they're pretty glossy overall.
