When I was at the Face Shop a few weeks ago, I picked up this inexpensive nail polish set for $6ish.
Inside are three different colours labelled 1, 2, 3. They are to be applied in layers from the inner nail bed to the tip of the nail resulting in a gradient effect.
The above photo is a test with only one coat. I found the sparkles in bottle three to be a little bit too large to effectively apply on the tips-only. Otherwise, I love the colours together! You can watch me test it out in this vlog.
The full line of Face it Gradation Nail Polish is available on Amazon!
