Pet Screen Door for Dogs and Cats (for cats and small dogs) 17cm (H) x 15cm (W) PD1923 This is a pet door that you install by modifying your screen door. I bought it intending to use it, but I ended up doing a DIY project from scratch, so I have this extra one to sell. The included screws are unused. I handled the main unit before installation, so I think there are some scratches on the smoked part. However, they will likely get damaged quickly once you start using it, so I don't think it will be a concern. This is a used item, so please refrain from purchasing if you are overly concerned about its condition. Shipping will be via Nekopos (a Japanese postal service), and I plan to use simple packaging, just putting it directly into an envelope.
