* The metal rollerballs fit easily and securely into place and the lids screw on tightly. No more worrying about your essential oils leaking in your purse or bag.
* These stainless steel balls are in their casing quite tight to prevent the balls from popping out or leaking. They may need to be worked in before using. To do this, put a roll-on ball in an empty bottle, press the ball down with your thumb and roll back and forth, or roll back and forth on a thick pad of paper or the inside pages of a book. Also the balls will roll quite easy once the oils are in the bottle and covering the ball.
*Can be used for essential oils, aromatherapy blends, perfumes, deodorant and massage oil.
