I like the glass bottle and the steel ball
I've been making my own essential oil rollers with these.. I like the glass bottle and the steel ball.. They roll very smoothly and consistently apply my mixes.<br />The additional tools, the dropper, the funnel, and the tool  for opening are a big bonus.<br /><br />I would recommend these to anyone wanting a reliable roller bottle<br /><br />thanks
