We all do it. You leave the lid off your polish for a tad too long and dangit, now it’s gloopy. Nail Thinner to the rescue! Drop a small amount into the bottle, give it a shake and voila. Good. As. New.

Does exactly what it promised! I purchased this to thin out some other branded polishes (holo taco) that just didn’t have the staying power.
I’m not a scientist, so I’m not sure if it’s the nail polish, or the thinner, but when added to a clear top coat the end result looked very slightly cloudy in the bottle. The top coat still applied clear and glossy though.
The nozzle is the best part of this product - it’s so easy to use.
Note: I’ve had one Kester Black polish for almost two years and it doesn’t need the thinner.

You get a lot of thinner (125mL), but I've only needed to use a few drops to thin out some of my older polishes that have thickened over time. While they are formulated with the Kester Black polishes in mind, I didn't have any trouble thinning polish from other brands.

I was dubious about this because other nail polish thinners I’ve tried in the past haven’t really worked, but I have so much faith in KB that I thought I’d give it a go. And it works! Just a couple of drops have given my Supersonic top coat new life, and made my glitter polish less gloopy. I’m so impressed!
