I haven't kept the box. I have the instruction manual. I only turned it on once. Operation confirmed. I received another one as a gift, so I'm selling this one. I bought it on Amazon for just under 7000 yen. There were a lot of reviews, so you might want to check those out if you're interested! Search for "Redido Dehumidifier Small Powerful [Dehumidifying, Humidifying, Air Purifying 3-in-1]" and you should find it.
