The classic Mini features a white ABS shell with letter storage. The shell of the lightbox is important for quality and durability. So is the front panel, made of strong acrylic, it is heat sealed onto the shell to last for years of fun use. The white LEDs are designed to give the most even and bright light, positioned perfectly to evenly distribute the light and never show spotting or dimming. The Mini Cinema Lightbox is made with only the highest quality materials and more LEDs than any other brand - Light Up Your Life! Every light box is quality checked and includes 100 letters, numbers, and symbol tiles and a matching white USB cable. My Cinema Lightbox was the first lightbox brand to introduce these fun gifts to the market!
