The Clamp Series by Drilling Lab is a collection of jewelry inspired by bicycle seat clamps. Currently, the series showcases two rings, one seamless and the other split down the middle. A screw completes each design while adding to the industrial look. Wear it on top to show off the hardware.

All of the components are available in black, silver, and gold, and each ring comes packaged with three screws, one in each finish, so that the wearer can mix and match. Minimalist in form and presentation, the design is sold inside six layers of cardboard cut no larger than a business card and held together by two elastic bands.
