Cu2+ is a strong, linear holo teal polish. The formula is quite dreamy! It just glides smoothly over your nails and provides full coverage with just 1 coat! I must say this polish had me perplexed for a bit. The polish first looked blueish to me and I couldn't figure out why it was names after copper. But, after observing it under different lighting I do see is more of a teal green than blue.
Shown below are 2 coats (just for good measure!) with no top coat. I used Silver Sweep from Sally Hansen and Pueen encore plate SE01A on my accent nail.
This is my first Chirality polish and it will not be the last one! Do you own any? Let me know what you think of them!
