You are buying the two blocks shown in the pics. Each one is over 12 lbs and is 6061 T6 Aluminum.

They are all nice and clean, like the ones in the pics, and I'm assuming would be considered scrap since it's not likely someone is going to need this specific design for some project they're working on.

I also have some other shapes and sizes of this same kind of Aluminum listed, in case you need something different.

With all that being said, if you have questions, feel free to ask.

Thanks, Bill
