ATC SCM 20ASL Pro Mk2 2025 - Black

Excellent condition, original owner, a little over a year old. I took them out of their boxes and set them where they are in the pics, and they haven’t moved since. There’s a small impression on the top rear of the left monitor (pictured) which is the only blemish I could find. My suspicion is it came from the factory like this and I'm only just noticing it. Either way, the monitors function perfectly. Will ship insured in the original ATC packaging with all accessories included.
