CO & Smoke Carbon Monoxide / Smoke Detector

Thank you for looking.
Although it has not been actually used, it was opened to check if it powers on and for photography, so it is treated as used rather than new.
The batteries have been used once, so this product does not come with batteries. Thank you for your understanding.
