Good price for what I needed
Size: 16'' x 43''
Perfect for the coffee table I was working on, adjust to the size I needed as I only used 2 middle pipes for a 36” table top. Good durable pipes. The down come slightly scratched up as they weren’t packaged in anything protective so I ended up spraying them with a matte black.
