Splash is from the Childhood Memories collection. In a clear base, this is jam packed with microglitters of holo blue, green and holo silver. You can put one coat over a base colour (like the ring finger in picture 2) or wear it opaque in 2-3 thin coats (other nails in picture 2). Because of the microglitters, it will be a textured look when dry, so a top coat is recommended if you prefer the glitters to really sparkle!
If they don't have what you're after, simple ask Caitlin!
All my polishes are 5 free (No Dibutyl Phthalate, Toluene, Formaldehyde, Formaldehyde Resin or Camphor) I have added ingredients to create a finished product that I have tested on my own nails.
