Black stainless steel electric kettle. Used for about a year since purchase. There is limescale inside, but there are no problems with boiling water, the switch, etc., and I think it can be used as usual. If you are concerned about the stains, you may want to clean it with citric acid, etc. Also, since I have discarded the original box, I will ship it in a different kettle box. Thank you for your consideration. - Brand: LIGHTEN - Color: Black - Material: Stainless steel - Included items: Instruction manual
