I recently tried the SinfulShine with Gel Tech nail enamel. I absolutely love this product. It’s a two-step application “gel polish”. It dries super quick, easy to apply and it actually lasts. I always find that my nail polish starts to chip after two to three days yet I have it on for the fifth day now without any chipping, shrinkage or peeling. The colour (step 1) on its own is very shiny. The topcoat (step two) will seal in the colour and eliminate any possible flaws. I am absolutely impressed. I tried the colour (Dark Room 1623) which is black.
