A3 tracing board equipped with high-intensity LEDs, practical waterproof design, and easy to use. As a functionality check, I have confirmed that it can be turned on and the brightness adjusted. I am selling it because I don't use it. Please only purchase if you understand that this is a used item. I will wrap the box in cushioning material such as bubble wrap before shipping. - Model Name: ARTON SMART TRACER PRO A3 Thank you for looking.
