At the moment I'm doing them in burnt real GR5 titanium. Might do a cheaper anodised aluminium version later, we'll see what the future brings.
Not yet, have to finalise the production costs, should have a price next week, but as I said before, being real titanium, is not going to cheap. As I'm not looking to produce 1000pcs, that will also add to the cost, being a smaller batch, but in the same time, will be something very rare so will hold value in time
