We have been searching for years for a translucent horn pane to use in lanterns and hornbooks. We've found it! These panes are just under 3" wide and about 4-3/8" tall and a little over a 1/16" of an inch thick. They fit our FL-3 Barn lanterns perfectly. Each one is a little different and some may have some white on the pane but they are mostly clear horn. When used in lanterns they are light weight and virtually unbreakable. Imported.
