Noborennya Barrier Free 2

I was asked to buy this to prevent escapes, so I purchased it. However, since we already have a screen door and a secure door for escape prevention, it was never used at home. It has been left leaning against something for about a year. Since it was just leaning, it has not been opened or closed. There is a little dust on the indented part (see 2nd image), and the pipe at the very top that extends has some minor scratches. There are also some line-like smudges on the back of the opening/closing mechanism (see 3rd and 4th images). Please only purchase if you have confirmed these details and agree to them. Overall, the condition is not bad. Thank you.
