Titanium Boone Titanium Cog Earrings Finish:Anodize Special (Describe in Comments) The ring shown is 8mmThese are the original cog earrings from 20 years back crafted from aerospace grade titanium. These are the patented cogs that started the company. They are so lightweight that they don't even register on all but the most sensitive scales. Hypoallergenic and very cool. We have several pairs of the Blue Purple and Blue Green Earrings in stock now ready to ship! They are about the size of a US dime. We offer the option to anodize them colors.
