Eric at Ivan & Co Jewelers sent me samples of the hex key chain a while back and I ended up really loving it. I'm not much of a key chain person but these are different. I kept it on my 1M key fob for a while and it ended up going with the 1M when I gave it away so I decided to get a few more made. These come in two styles, Bronze and Silver, both with brushed finishes. The silver key chain is 935 silver which is a bit more resilient to tarnishing than normal 925 sterling silver.
They're handmade and OG spec which I think more than justifies the price of these.
