See this brush? This is what you need: long and skinny. Don’t get some stupid fat tipped squeeze pen, a sharpee, or even try to use your regular polish brush. Puh-lease! The long brush is the only ways to get that zebra kinda stripe. If you can’t find some crappy cheap nail art polish like mine, you can totally use a regular thin brush from the craft store. Just make sure you dunk and rinse it thoroughly in nail polish remover after each use.
