…O.P.I!! O.P.I’s clear top coat is by far the best top coat for durability. After being disappointed by Revlon’s Quick dry top coat apparently having ’30sec drying time’, which is more appropriate for the time before chipping, I needed a replacement. I recently visited a nail bar in London to have the basic file and paint where they used O.P.I polishes, and my nails showed no evidence of wear and tear even after a week. So I thought I’d try it for myself, after purchasing the O.P.I top coat in duty-free for around £10 I applied it on top of a Chanel polish and the result 5 days after (see picture), they look just as fresh as the day I painted them.
