Darbla Posted February 2, 2019 Share Posted February 2, 2019 You can get rollerballs with a plastic ball or a metal one, with the metal of course being more expensive. So have you noticed problems with the plastic that would make it better to invest in the metal ones? Bottles on both are glass. I'm looking at ones from WSP but I may look at others.
