Callum Ring Set (set of 3)

Very nice minimal rings works for daily wear wearing this for almost 21 days no colour tarnishing

I like the look of the rings, they are affordable but the problem being that the ring are blackish from the inside, I tried to wash it, i could get rid of some of it, but the crevices are still black. I hope it lives up to the promise of being anti tarnish otherwise it is money down the drain.
