Perfect for essential oil blends!
on February 4, 2014
I'm new to essential oils and wanted to try mixing some with carrier oils. These are the perfect containers! Please note: The roller ball is virtually impossible to put in by hand. The solution is simple: Put the ball into the opening, then just screw on the bottle lid. You will feel some resistance but just keep going. It easily pushes the roller ball into place!
