Vintage 1930s 1940s etched gold cufflinks with box almond shape can be engraved

Set of 2 cufflinks, probably gold plated or gold filled as it was called in the past. One side has an all over design and the reverse has a cartouche for a monogram to be engraved if desired. 3/4 inch long Slight discoloration, please look at all photos. Comea vintage box that is probably not original to the cuff links.
