I'm going to show you two Catrice nail polish swatches today. The colors are gold and silver looking. Both colors are great as a base for crackling nails ;).
These are sold at the Dutch drugstore, Kruidvat. They are €2,49 each.
The brushes are very thick. The brush from the back to black nail polish is slightly thicker than the other one. However, they are easy to work with and they aren't streaky at all. If you do it correctly, you will only need one coat. The coverage is good of both nail polishes.
I really like the back to black nail polish :D, love the color! Which one do you prefer?
