This is a USB-powered 3D LED digital clock. The large numbers are easy to see, and it can be placed on a desk or hung on a wall. Since there is no instruction manual, I have researched and included images. I have not been able to confirm the alarm function, brightness adjustment, or temperature display. [Functions] ・Time display ・Alarm function ・Temperature display ・Brightness adjustment ・12/24 hour display switch [Condition] ・Operation confirmed ・No noticeable scratches or stains (see photos) [Accessories] ・Main unit ・USB power cable ※AC adapter, button battery, and instruction manual are not included. [Note] USB power supply is required. Since the model number is unknown, it is sold as a general-purpose product. Recommended for interiors, bedrooms, living rooms, and offices.
