Review on Premium 3Ml Cobalt Blue Glass Roller Bottles With Stainless Steel Roller Ball And Bonus Droppers - Set Of 12 by Donald Phi

I love the color and the idea of roll-on glass bottles and stainless-steel balls. Unfortunately, they don't work. I have filled the bottle to varying levels and even primed the area where the ball is, since there were no directions on how full to fill the bottle. Nothing comes out on the ball. I even tested it on a piece of white paper in case I was missing seeing it on my skin. There was nothing there. Additionally, the ball and stopper are very difficult to push in. It is as though the ball is too tight in the plastic holder and the ball can't move. Disappointed. I was going to use these for samples of product I was going to sell.
