They are beautiful and although I’ve only used them a couple days so far, they don’t seem to leak at all which was a primary concern of mine.

It’s been a few weeks of use on several already and there have been no cracks, no breaks, no dusting of the steel roller balls that I’ve added oils to

So easy to use and products so well!! The balls don’t get stuck and they don’t leak either! I’ll be sticking with this brand for all my bottles!!

I’m using mine so I can easily apply vitamin e oil to my skin to combat dark spots. Comes with 2 funnels, funnel holder and two extra roller balls.
