This half scale window is designed by Bespaq™. It will fit half scale openings in most dollhouses. It is pre finished in white and uses micro glass in lieu of acrylic. A finished interior trim ring is supplied with each window which can be used as a template as well as the finish trim. Just imagine having the most stylish. realistic and highest quality window available....and not having to spend hours finishing with two or three coats of paint and then trying to remove unwanted drips from the plastic window panes. The window fits openings measuring 1 5/16" wide and 2 13/16" high.
