These seem pretty fancy! Here is a pair of vintage silverplate lemon slice squeezers. Open them, add your lemon slice, and squeeze together. There is a little opening for the juice to escape. No makers marks or other marks.
We do think these are silverplated because they were tarnished but shined up quite a bit with polish. There is still light tarnish in some spots. There is light corrosion on the lip of the juice opening.
2.5 inches across and 2.5 inches high when closed. 4.875 inches long when open.
You get 2 pieces.
