DJ On Board is from Essie 2016 Shimmer Brights Collection. As, the name suggests this collection consisted of shimmer polishes. This particular polish is a bright lilac shimmer. It is glowy and beautiful.Essie polishes have 2 different brush sizes (I think I have read somewhere that thinner brushes are produced in the US and wider one in Europe, but it could be other way around). My bottle has a thin brush, but I prefer their wider brush, as I have wide nail beds. If you are buying from places like TKMaxx/TJMaxx, you could come across both versions and the easiest way to tell without unscrewing the cap is, if the name label is on the top of the cap the brush is wide. If the name label is on the base of the bottle the brush is thin.I was disappointed with the formula. The first coat was difficult to apply it went on patchy and uneven. If I tried to go over and correct it the brush would pick up the colour underneath and make it even worse. The second coat was much easier to apply, but I still had a little indent at the base of the nail the starting point of the brush. So, I applied the 3rd coat just to cover up those indentation. The 3 coats took longer than usual to dry, I woke up with a sheet mark on one of my nails. In conclusion, I would repurchase this polish for the colour/finish, but the formula is not the best, so prepare to be patient.
