Heat-resistant protective sheet for IH cooking heaters, with a blue leaf pattern. - Design: Blue circles with leaf and fruit patterns - Size: Approximately 22cm in diameter - Material: Heat-resistant plastic - Application: Protective sheet for IH cooking heaters Thank you for viewing. I used it once, but I realized it was unnecessary because I wipe the IH after every cooking session. Therefore, it's practically unused. It will be shipped folded. The creases from folding will disappear after a while.
