I purchased this at the Tableware Expo held at the Tokyo Dome several years ago. I have also lost the instruction manual, so I don't know the details, but I remember being told by the shop staff that it was a shop specializing in Echizen lacquerware. I apologize if this is incorrect. I used it a few times, but my family has become smaller and our lifestyle has changed, so I decided to sell it as we no longer use it. The size is just right, It fits well in the hand and the taste is good. Thank you for your consideration. Size: Choko (small cup) 8x6.5cm 　　　: Condiment dish 8x1cm
