Rose Quartz Beauty Roller

This is easy to fill, and the top goes on with a bit of force. My only concern is trying to get the roller-ball top off when it's time to refill. It would be so much nicer if the roller-ball section was also threaded for easier removal. UPDATE: After less than 2 weeks of use, the plastic ring holding the quartz ball in place split, making it useless. I was using this for castor oil, but there was nothing in the documentation saying thus was a bad idea, so I have no idea why this failed so quickly. Diwngrading to ONE STAR.

Perfect for what i want to use it for, came as described and great quality.

The plastic holding the ball in place split within hours of the first use making this completely useless
