Upgrade from plastic to stainless steel rollers that last longer and control oil application better.
These stainless steel rollers fit our ⅙ (5 ml) and ⅓ oz. (10 ml) roll-on vials. Roll-on fitments work best when the essential oils are diluted with at least an equal amount of carrier oil.
Quantity: 6 rollers. (Roll-on vials not included.)
