This is a lid that was placed on top of soba noodle bowls when delivering food in the Showa 40s (1965-1974). They stopped being used after the invention of plastic wrap, so there are many left. It's a product of old Japan, so the craftsmanship is excellent. There are some areas where the paint has peeled off. See photo ⑤. Use it simply by placing it on top when it's a hassle to use plastic wrap. ※This is only the lid; the bowl in the photo is not included. Diameter: 20.5cm Inner diameter: 19.3cm Thickness: 1.5cm #3-49
