Linen L, vintage knob specification. This is a genuine Japanese product with a serial number, but it has already been registered, so the serial number cannot be provided. If you understand, and if you wish, I can cut out the serial number portion and include the instruction manual in the photos. It's quite heavy, and I hesitated about whether I could use it, but I bought it anyway. It cooks very delicious rice in a short time, so I hope to sell it to someone who is also hesitant. I used it for about a year purely for cooking white rice and did not use it for mixed rice dishes. I washed everything by hand, dried it properly, and took good care of it, so the condition is very good. However, as shown in the last photo, there is a chip on the edge of the lid. Please confirm this. There is no rust, and there is no problem with use. I am selling it because I bought a different size. I would like you to use it, so I am offering it as cheaply as possible. Thank you for your consideration.
