The Sephora Formula X Paint Party ($47 CAD, exclusively at Sephora) is a set of 24 travel-friendly press-pods full of Sephora's best cream and pearl nail polishes. Although don't own any of the Formula X polishes, I'm already a huge fan. I always swatch them in-store but I'm extremely indecisive so I never decide on which colour I want. The Paint Party set is a great way for indecisive people like me to get a feel for what colours look best on my fingers.
The Press Pods come in a paint-can shaped container. I think the packaging is pretty ingenious and I'll be re-purposing it into a makeup brush holder later on.
