The gel sheets are not included. They are not enclosed, so you will need to obtain them separately. Please note that the box is also not included. Operation has been confirmed. I purchased it in 2023 and used it for about six months. I don't plan to use it anymore, so I would like to sell it to someone who needs it. No comments necessary, immediate purchase is welcome. Please refrain from price reductions. For those who understand home storage, Thank you very much.
