1930s butterscotch Bakelite sash buckles

1930s butterscotch Bakelite sash buckles. Each piece has two narrow openings for a sash to pass through. Wear together, separate, or gift one to your bestie. Heavyweight, tested. There is a 1/4” chip near one of the openings. It’s hard to tell because of the marbled affect but they each might have an interior pressure crack. The surface is perfectly smooth and there’s no signs of surface damage but it’s worth mentioning. MEASUREMENTS: 2” x 2 3/8”
