Snap cufflinks are fairly easy to date as they become popular in the 1920s and faded out in the late 30s. Also known as Kum-a-part, Snap-Link, Lion Brand, Jem-Link, Jiffy-Links, the list goes on - snap together cufflinks are highly desirable by collectors and its easy to see why. Once placed in the double cuff theyre easy to snap together and release when needed. This pair is intricately decorated on a dome of etched / moulded glass with gold and black paint forming a 4 petal design.  The wide of the cufflink face is 14mm diametre.
