This is a sliding door stopper that can be used for window locks. I purchased a set of 5 on Amazon and used 2. I am selling the remaining 3. There are 3 alcohol wipes remaining. The main body and tape are transparent, making them inconspicuous and blending well with the interior. The double-sided tape used is from 3M. Also, it is only 5mm thick, so it can be used on various windows.
