Nail Polish Thinner

I always knew there was a thinner in existence but never saw it in the shops. This is KB thinner is exactly what you’re after for those favourite polish colours that are getting down to the last few uses. I had a red KB from at least 3 years ago and stopped using it because it was getting a bit harder to apply. Few drops of thinner and it’s good as new.

Works a treat to thin down nail polish that needs it. Amazing.

Great product just a few drops save my old nail polish :)

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.
