Marc Jacobs will debut his fall 2016 collection on Thursday and while we simply can't wait for new designs from the beloved American designer, there’s something else Jacobs-approved we’ve been enjoying immensely.

The extra skinny brush ensures each and every lash is coated, resulting in a look that’s far from boring.
