This item was purchased at Kyoto Nishiki Aritsugu Knife Shop. It was used once and then stored. The pure copper surface shows some discoloration due to oxidation, but it can be restored to a shine by wiping it with edible citric acid. You can see it's like new by looking at the shine on the inside. With copper prices continuing to rise, it may become difficult to obtain. Please take this opportunity to purchase. Since it has been used once, I am classifying it as gently used. If you are looking for brand-new quality or are very particular about condition, please refrain from purchasing. Thank you for your understanding.
