Yes yes yes, beer drinkers and bikers united in one product.I made it from a portion of a recycled bicycle gear welded to a re-purposed steel bushing. It is oxidized and hot waxed, and totally functional. I also attached a key chain to it for easy access. It comes in a reusable tin lined with a piece of recycled bicycle tube. Sweet intro price of $25, get em before I raise the price! Since I use a variety of types of cogs, each one is different, but appealing. The picture above is to give you an idea of scale and function!
