Purchased in 2021. Used it connected to a laptop. No outer box, inner box, or [accessories] such as carrying pouch, warranty, or instruction manual. I will pack it carefully to prevent any gaps. There are no obvious scratches, but there are some wrinkles from use. I am a non-smoker and do not own any pets. I will wipe it down before packing.
