Thank you for viewing. This product is a "Carving Knife Non-Slip Sheet Set." It has a compact and easy-to-use structure, and as shown in the fourth photo, the carving knife is easy to remove. I used it for about three months in elementary school classes, but I am selling it because I have no plans to use it anymore. I used and stored it carefully, so there are almost no scratches. Please check the condition of the product in the photos. Thank you for your consideration.
