I purchased this from Felissimo many years ago. It's compatible with direct gas flames. I'm not sure about IH (induction heating). There is no instruction manual. Since I've used it on a gas flame, the bottom has burn marks and discoloration. The brown one wasn't used very often and is relatively clean, but there are stains that won't come off. The other three were used frequently, so they have noticeable stains and burn marks. The orange one has chips on both handles. No individual sales. Please feel free to comment if you have any questions. I will ship via either Yu-Yu Mercari Bin or Raku-Raku Mercari Bin. ⚠⚠If you want to receive it at a convenience store or post office, please contact me in advance. ⚠If you have any specific requests regarding shipping methods or dates, please be sure to consult with me in the comments before purchasing. I may not be able to accommodate requests after purchase. Thank you for your cooperation. #Yu's Daily Necessities #Yu's Felissimo Items
