So sorry it took sooo long to get back to you.... it is nsi top coat in a polish bottle with coarse spectraflair added... it can be put over any color to get a great holo effect.
They are my nails...I put a base coat of Sally Hansen X-tream color "celeb-city" then 2 coast of spectraflair topcoat....and a bit of loose holo glitter at the smile line point to give a fade look....
