This pair of Bicycle Chainring Cufflinks designed by GothamSmith is a perfect gift for bike enthusiasts. It’s just as big a hit with people who like to collect different kinds of cufflinks to go with their French cuff shirts. It’s 3D printed and made to order in the USA by Shapeways. They’re extremely visually appealing and sure to catch the eye of someone you’re hoping to impress. This is a recyclable environment-friendly product, so you get to look good and help save the planet while you’re at it. The cufflinks are available in three types. One is an antique bronze finish, another one comes in stainless steel, and the third one is cast sterling silver made from a printed wax positive.
