I have a UV light and polishes, so I painted my nails with black gel polish and then applied a small amount of the powder to my nails. I like how pigmented and "dense" these are. You can just tap a tiny bit in the container and just keep tapping it over the nail and it covers it! I thought I would have to use a lot of powder to cover my nail, but it was just a small amount that was able to spread and achieve the mirror effect! I was very pleased how easy it was and how good it looked!
With that said, I do think the silver looks better than the gold. I'm not sure if another (lighter) base color would be better for the gold. It just didn't look as "bright" as the silver. It still looked cool and had a mirrored effect. But it wasn't as dramatic as the silver. It was more "muted" I would say. I think the gold would be great if you are doing a design on your gel nails (silver would be good too).
I'm pleased overall. These worked well and delivered on the "mirror" effect for the most part. It was simple to do too (after watching videos since it didn't come with instructions). Happy with how they look!
