Review (5/5): Not bad.
I bought two bottles of Northern Lights Top Coat Gold. The glitter is somewhat sparse, and it takes a while to get it throughly mixed into the polish. I liked how quickly I could remove the polish with acetone. No scrubbing to get it off.
I got these as sort of a replacement for three Avon Snow Globe polishes that I own. I have had them for at least 14 years. They still work, but are old, and won't last forever. I liked the Snow Globe polishes because they were holographic, something rarely seen back then unless you bought Sally Hansen Nail Prisms or Magical polishes (Neither of which I bought and now regret not getting them). The Avon polishes are like water and require a little bit of shaking since the glitter is on the bottom. The Northern Lights polishes are a little thicker but require lots of shaking to get a good mix of glitter. Also, the Avon polishes have twice the amount of glitter in them as the Northern Lights do. If you are one of the few that bought the Avon polishes back then and are looking to replace them, these will do ok. Or if you are just looking for a holo topper these are still ok. Just keep in mind that one coat of Northern Lights makes for a sparse glitter topper.
