I've been trying to get into the habit of painting my nails all the time, and trying not to worry so much about putting a top coat on. I use Seche Vite and while I love it, it takes ages to dry and takes planning to do my nails. To this end, I've recently used a couple of matte polishes as they don't require a top coat.
This is a Zoya polish, it's called Phoebe. It's a gorgeous neon blue matte. I really love Zoya polishes
This is a Japanese brand called BK. I got a whole set all in neon colours. This is a fantastic highlighter pink colour.
