Is the ball glass or plastic?
Do you carry replacement caps and rollers for these bottles
How does this roll-on perform with on oil based product? We have used another vendor for this and they leak. Thanks, Glenn Walker
I need to get the label dim size for these so I know prior to ordering. Thank you kindly! Jen Dunn
What type of plastic is the ball and fitment made from? Are there different material choices for these items?
Can I ask what size is the ball? Like in mm? And also can that be replaced if the ball falls out?
