This size eye dropper is designed to fit our 4 oz glass bottles. The dropper is incorporated into a threaded cap which can be screwed onto the top of the bottle.
Please note: Exposure to certain super-strength flavors and essential oils may cause the rubber to degrade. For this reason, we do not recommend long-term storage of the bottles with the dropper tops as the cap.
