A fab pair of mid century cufflinks by Niels Erik From, Denmark. Stamped to the side of the posts with 'Sterling Denmark N.E.From 925S' (925 grade sterling silver). 
Mid century era (apx 1960s-1970s) and very much in a Modernist/Brutalist style (smooth and simplified but blocky). The smooth surface area is satin brushed and the indented contrasting pattern is blackened. Each rectangular shape is 19mm x 9mm. 
Very good for the age, both have a straight hallmarked stem/post and a polished free-moving oval back toggle; both toggle freely. They weigh 13 grams total.
