OPI Gel Polish French Manicure Tutorial 

They r using OPI # 6 flat gel brush . There r two # 6 on their site you would want the one that says “ flat “

I’m guessing you can. I could never freehand, especially when using my non dominant hand. I did see in another video that you should apply a base coat before the gel so you get a smooth line when removing the guides.

It’s fine to just use base, white and top ☺️ it just looks more “perfect” when there’s a pinkish nude underneath to even out the nail bed.

Essentially isopropyl alcohol with other ingredients.
