This is a Noda Hororo oil pot and activated carbon cartridges (6 pieces). This is a Dinos-exclusive color. The product arrived, and I put about 1 cm of oil (new oil) into the pot, but then I realized the size wasn't right, so I washed it thoroughly and stored it. How about it for those considering purchasing a new one? 〈Activated Carbon Cartridge〉 It removes "dirt" and "odor" that cannot be removed by the mesh filter that comes with the oil pot. It can be used repeatedly about 10 to 15 times, making it economical. (Reference Price) Pot: 6,600 yen Cartridges (7 pieces): 4,620 yen This is for 6 pieces.
