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!

Standard

Bottle was leaking a bit when I received it but hasn't leaked since I put the dropper on it. Works so well to thin out nail polish (have only tried on Kester Black polishes) but they're never quite the same afterwards. This bottle will last me forever.
