Color: Black系 (Black-based) Mlte Flash Warmer MR01FW This is an instant water heater from CB Japan that dispenses hot water in about 2 seconds. I purchased it from the official manufacturer on Amazon, but it had an initial defect, so I had the product replaced by the manufacturer. (I was told that refunds and returns were not possible.) A new one arrived, but I am already using something else, so I am putting it up for sale. I will send the new replacement unit, which was sent from CB Japan, in a completely unopened state.
