Sally Magpies if you want one. Did I mention they glow under UV light?
For this swatch, I decided to layer it over a gradient of BYS - Pink Panic, and Sally Hansen CSM - Lavender Cloud. This is 1 coat, with a little bit of dabbing and pushing to get a good coverage. In my experience, all of the neon glitters I have tried (especially the larger ones) like to stick together sometimes. I don't really mind that though, as it means I always get a good amount on each nail, and it was a breeze to get these ones where I wanted them.
To be honest I think I may even prefer it - I like to have some control over the placement!
