Review on 🖼️ A4 LED Light Pad: Ultra-Thin Tracing Light Box with Stepless Dimming - Perfect for Artists, Sketching, Animation, and Diamond Painting by Lori Aguirre

Glad they've finally come out with slim and portable light boxes that don't look like the clunky old ones. I bought it because it was the only truly portable device I could find - it uses AAA batteries as well as a USB cable. Many others say they are portable but require a USB cable to work. The only criticism is that the on/off button is not recessed. I can't tell you how many times I've bumped into something and pushed the button to turn it on while I was in the case draining the batteries. It's a bit pricey, but good if you're looking for portability.
