I am loving this natural glazed mani (which is so unlike me)! It’s packing subtle sparkle but mega shine, and all the fresh vibes that are absolutely perfect for Spring. I’ve been rocking it for three days and I’ve gotten so many compliments! It’s even better in person! Here’s the combo! Two coats of Baroque topped with The Mermaid Effect, from the new top coat collection (all by oliveandjune ).

Long lasting, yes!

I am so pleased with all the Olive & June products I purchased. The Poppy is so helpful, the polishes stay fresh and chip free for about ten days and the colors are lovely.
