I've used it a few times, but I haven't used it since, so I'm putting it up for sale. I've thrown away the instructions and box. I found the following information on the website where it's sold, so please refer to it. There are also other points to note, so I recommend that you also search and confirm them before using it. Material: Enamel steel plate Notes: The body, handle, and knob become very hot while boiling water and immediately after boiling water. There is a risk of burns, so be sure to use oven mitts or a cloth. (Usable: Direct fire / Not usable: Microwave, dishwasher, IH) There are a few scratches on the bottom, but since it's hardly been used, the condition is relatively clean. (This is a personal inspection, so there may be oversights.) Please consider this, keeping in mind that it has been stored at home and is a used item. Thank you.
