Loki stopped making the delrin, and instead carry their regular stainless rings that were sent to OCD and Cerakoted to match the ProVari black or zombie. I have one - I would have gotten a black one from ProVape, but I ordered the Loki one week before ProVape came out with a black one! It's very nice, just a little pricey!

I have two black Loki rings and like them, but they are made of Delrin (as are the Loki white ones, the rest are metal). Aren't all the ProVape rings made of metal?
