House Industries by Hasami porcelain. I received this item after it had been used a few times, but I haven't used it much myself, so I've decided to list it with some hesitation. It seems to be discontinued now and is difficult to obtain. I will also include the original box. Please be aware that the box has some stains. Base: Navy blue H pattern: White There is some tea stain, but I am listing it as is because some people may not prefer to use bleach. If you are concerned, please handle it yourself after purchase.
