I bought this, but it was too big and got in the way of my sink, so I'm selling it. I used it for a few minutes and then removed it, so it's practically new. I removed the filter and let it dry for a few days, but there might still be a little water left. You might want to run water through it for a few minutes when you receive it before using it. The original box is not available, so I will pack it with the instructions in bubble wrap for shipping. Amazon price: 3,975 yen - Type: Faucet water purifier - Color: White - Included items: Filter - Function: Water purification - Design: Cylindrical Thank you for looking.
