Have seen a pair such cufflinks before? It was one of the popular cufflinks during the the early 1930s. The reason for such cufflinks is that you can easily ‘fix’ a pair yourself in emergency and it is cheap.
It was also considered to be one the earliest novelty cufflinks can you imagine.
Well, I bet you can fix a nut to a bolt together Joe!
Now who say’s cufflinks must be expensive!
