Caps only (Old style with greater EO flow) – Set of 6




These black caps fit 5 and 15 ml bottles; we used them for years, but have recently “retired” them because they are more prone to leakage in transit; if you are not mailing oils, these caps work well.   Our new caps look like little “top hats”, with a thicker, rounded tamper-proof rim at the bottom; these in the set of 6 have a rim that is straight down from the body of the cap, it is not rounded.
