Just a few drops to thin out thickened polish.

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.

Magic!

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!

Great Product

I had a couple of favourite polishes that had gotten a bit gloopy. The applicator was great and now my polishes are back to normal! Breathes a second life into them which is amazing. Thank you!

Worked a treat

So far I've only used the thinner on some old base/top coats that were super gluggy, and it worked a treat to fix the consistency and make them usable again! I stupidly didn't see that the thinner comes with a little dropper on the cap, and I ended up probably pouring too much in but it wasn't an issue. Will use dropper next time!
