These new Wafer Lightboxes were a highlight of the International Art Materials Association trade show this past spring. Not only are they incredibly thin at just 3/8" thick, they also have a dimmable LED light, perfect for controlling the amount of light needed for each project. A built-in ruler helps with creating lines, and the unit is powered by an AC transformer (included). Stays cool to the touch. 19"x14" with a tracing area of 11"x17".
