These fit our 5ml and 10ml bottles and may be purchased with the bottles in your order, so you can change them after shipping if desired. Includes stainless steel roller ball in black plastic housing and black smooth cap as shown. These will not fit most other similar capacity bottles. While we have never received a report of our reducer inserts leaking, these roller type may leak. Do not turn bottle completely upside down to apply. 

The plastic reducer can be pried up with a blunt knife then removed, and the rollerball insert pressed down into the bottle. We recommend wrapping a paper towel around the bottle while holding it firmly in case of spills.
