The product is designed as a notebook screen protector with anti-reflection properties and is self-adhesive. While it is generally compatible with touchscreen devices, it's crucial to ensure that the protector does not interfere with the touch functionality. However, I'm not completely certain about its specific compatibility with the Lenovo Ideapad 5 2-in-1 touchscreen without further details from the manufacturer. It's recommended to check reviews or contact the manufacturer for confirmation.
