Copper water bottle and cup set Both are made of pure copper, with no plating on the inside. Purchased on Rakuten in August 2024. The water bottle was worth 8,880 yen, and the cup was worth 2,990 yen. (Please check the purchase history image in the 9th photo) Used only a few times, but there is a small dent on the bottom of the bottle. Also, there is some discoloration of the oxide film, which is a characteristic of pure copper products. (Please check the condition in the 5th to 8th photos) Please understand and agree to the fact that these are used items before purchasing. #
