Crafted with a side cutout in the shape of a rectangle, allowing seamless insertion of a USB light strip. Additionally, featuring a serrated back for effortless hanging. Their lightweight design permits easy hanging with just a thumbtack.

Pro Tips:

Utilize a hot glue gun for securing the LED strips, offering a swift and tidy method. I've found this to be the most efficient technique. Some LED strips may lose their adhesive properties over time, leading to detachment.

Apply a silver or reflective material on the rear surface. Personally, I've employed silver tape, but various alternatives exist. This facilitates even light distribution throughout the box, enhancing brightness.
