An eight-light window with integrated shutters from Houseworks measures about 4-1/16" wide by 5-1/4" high and fits an opening 2-9/16" wide by 5-1/16" high. This window works best with 3/8" thick walls and is designed for use in one-inch (1:12) scale dollhouse miniatures. Unfinished wood. HW5003 does not include any plastic or Plexiglass "glass" for the window panes. If you would like to have "glass" in your windows, I suggest you save stiff plastic packaging and cut a piece to fit the window frame (just be aware that some plastics tend to yellow with age). If you would prefer a better quality window, I recommend ordering a package of KSE1310 (sold separately).
