This is an LED presenter made by the manufacturer Inateck. It uses an LED light source, so it's safe for the eyes. My child needed it for a school presentation, and I bought it on Amazon, but it's been unused since then. It charges using a USB Type-C cable. I tested it, and it seems to work fine, so I'm listing it on Mercari in case someone else can use it. The instruction manual is missing. Is there anyone who understands that this is a used item and is willing to cover the shipping and packing costs? Also, the included gray pouch made of brushed material had my child's name on it, and when I tried to wash it off, the brushing became thin. Please see photo 4.
