I have a few shirts with a single cuff that require cufflinks. The problem is, I really dislike wearing cufflinks. I find them bulky and overly formal. One of the shirts came with a kind of double-button threaded together to form a cufflink. I've since lost this, but it seems like a great solution for me. Is there somewhere to buy these items? What do you call them? Any time I've searched "button cufflink" I've gotten silver cufflinks that look like buttons, not actual buttons as cufflinks. Thanks!
