This is a pair of classic men's cufflinks with an unusual and highly collectible stamping error!  The style is consistent with the popular vintage brand SWANK, featuring an elegant silver-tone external oval with cutout silver-tone internal oval.  

The back of one of the bullet-toggle closure, which is typically stamped "SWANK," is clearly stamped with the misspelling "WANK." This rare manufacturing error makes this set a unique novelty item perfect for Cufflink collectors looking for unique errors or someone with a sense of humor looking for a witty accessory. This error is rare and humorous adds significant novelty value.
