You will receive 24 Glass Roller Essential Oil Bottle Inserts WITH Black Caps. (without black caps, your oils or liquids will evaporate)  Beware of ads with NO BLACKCAPS!
 
GLASS ROLLER INSERTS  are great for Thinner to Mid-Grade oils with FCO.    
 
NEW DESIGN AND MATERIAL:  (May 2019) Roller Inserts have been redesigned to fit tighter into the bottleneck. The black collar material has been changed and resized to ensure balls do not fall out and allow for removal and cleaning for re-use with different oils or blends.

GLASS ROLLER BALL INSERTS fit 99% of doTERRA Essential Oil Bottle Sizes 5ML and 15ML.  (if you run across a bottle that my rollers do not fit, PLEASE send me a message so that I can list them on my ad for future customers.  TY)

Rollers are reusable and can be easily disassembled by poping the black collar off and cleaning with alcohol before changing oils or other liquids.

Great for turning all your empty EO bottles into roller bottles by using these roller inserts.   Give DIY rollers to your family and friends.

BOTTLES IN THE PICTURES ARE NOT INCLUDED WITH YOUR PURCHASE.
