Chainmaille is my anti-drug. I'm too addicted to try other drugs. =P
Closures look good, but I noticed some marks on the anodized/enameled (You didn't specify, but in any case, the colored) rings. If you just hold them in your pliers, don't squeeze, just hold and bend, you'll have a better time of it and not mar the rings.
And I was much amused by Myrdda's comment... Byz is clunky but CIR is not? Haha! Besides, Byz isn't clunky if you use tiny rings. =]
They're anodized. And that's probably because my pliers have teeth. Sometime soon I'm gonna go out and get myself some pliers without teeth.
