I am so obsessed with silver holographic polishes. Today I have OPI DS Sapphire, which is a blue based silver holographic with a little bit of pink flash.
I started with Morgan Taylor REACTmax in Original, 2 coats of polish, and finished with cuccio High Gloss top coat. The formula was a dream to work with.
I have a couple of back up bottles of this that I eventually want to sell.
