This is a very good fridge. I have kept it unused for a long time; it just needs a gas refill, and everything else is perfectly fine. You can inspect it as much as you like. Inside, some chambers are made of copper, while others are aluminum, but this one has copper, which is its best feature. It has a drawer system, and I hope you won't regret buying it. The marks you see inside are just from being left unused for a long time; you can just scrub them off.
