Purchased at a dog and cat event in May 2025. My pet initially drank from it, but then hardly used it, so I'm selling it as it's a waste. There are no noticeable scratches or stains, but please understand that it has been used once. I searched the manufacturer's website and found that the main unit sells for 8,000 to 9,000 yen, and the cartridges are around 1,900 yen. I purchased it at a discount at the event, and since it's a used item, I've set the price accordingly. Please feel free to ask if you have any questions. No returns or refunds. Will be shipped with simple packaging. Thank you.
