We had a lot of requests at Renegade chicago for cufflinks. After a bunch of research we decided that if we were going to offer cufflinks we would need to design and build them ourselves. There are prefabricated cufflink blanks available, but they are in my opinion, junk. Anybody with a hot glue gun is making cufflinks out of them left and right, just do a search for cufflink on Etsy.
We designed the best cufflink we could produce. Check out the pic. The cufflink is stainless steel and oak (wood).Cufflink #1.
