This is a security measure for windows. It's used with two, one at the top and one at the bottom. For those whose one has broken, or for those who forgot to buy one, how about it? Color: Bronze ☑︎ Installation size 28mm〜42mm (1.10in〜1.65in) I accidentally bought this, so I'm selling it. ☑︎ I will use recycled materials and ship with simple packaging. Since the thickness is borderline, the shipping method will be undecided.
