Quickly and easily put roller fitments into vials with O-Presto.
Roll-on vials make it simple to apply prediluted essential oil blends to the body. But, it can be difficult to insert the roller fitment when filling or refilling your vials. O-Presto makes it easy! And it works with our 1/6 and 1/3 oz. roll-on vials.
Features: 2 slots—shallow for 1/6 oz. (5 ml) vials; deep for 1/3 oz. (10 ml) vials.
Instructions: Fill a roll-on vial with oil or other liquid, leaving room for the roller fitment at the top. Lift the pressure bar. Place the vial in the appropriate slot. Set a roller fitment (including the ball) on top of the vial. Press down on the pressure bar to push the fitment into the bottle. Screw the cap onto the bottle, and you're finished!
