Milwaukee was once known as "the machine shop to the world."  Even today, a certain blue collar romanticism remains.  The idea of wearing a machine on your sleeve could only have come from a place like this.  HollenWolff self-retaining cufflinks will only open when held "north/south."  Which means they can only be operated by a man who knows which way is up.  This mechanical metaphor was built into HollenWolff cufflinks for a reason.  Like Excalibur and the stone, it only works for the man who has found his "True North."  Utilizing high integrity materials like surgical grade stainless steel, with experience gleaned from a half century of industrial ball bearing manufacture, HollenWolff creates cuff links of uncompromising quality. This set of Harley-Davidson 110th Anniversary cuff links comes in a handmade leather case inside a black aluminum box.
