This is a photo frame that lights up, perfect for displaying precious photos. It's easy to use with USB power and looks beautiful. Great for baby photos too! Although assembly instructions aren't included, you insert the photo between the clear acrylic plates. Then, fit the light panel into the wooden base, connect the USB to a power source, and place the acrylic plates on top. Secure the side wooden pieces with screws. There are no pre-drilled holes in the wood, but you can create them with a screwdriver. It's postcard size. Thank you for looking!
