I'm selling this item because I bought it a few years ago and only used it a few times. It's 26mm in size. It comes with the box and instruction manual. The box has some discoloration and marks from removing a sticker. It's designed to prevent burns, so I think even beginners can use it with confidence. Please consider this item with the understanding that it is a used product. #Iron #CurlingIron #Panasonic #26mm
