There are few things I love more in a nail polish than a holographic effect. As far as holographic glitter goes, Revlon has really done a great job with this one. The glitter is dense enough that a scattered holo effect can be achieved with a few coats.
With three coats this is just stunning!
I’m kind of indifferent to the nail art pens. They are easier to control than a nail art brush but they aren’t actually easy to use. They wrk well for dotting but I struggle with drawing with them. The pink and chartreuse colors both faded to nearly white over the course of five days.
