Therefore, the color may have changed due to the outside temperature when delivered in low temperatures. There is no problem with the function, so please wash the item with lukewarm water and use it after bringing it to room temperature. This was received as a gift in August 2025. I am unable to use it because it seems a shame, so I am selling it.
