Nice to have-fits on my 4 ounce and bigger bottles of essential oils
I am an essential oil enthusiast with at least 100 bottles of essential oils in varying sizes and bottle from a variety of different venders.I've tried these reed diffusers caps with holes in the middle for diffusing and they only seem to fit my 4 ounce and 8.5 ounce essential oil bottles. They don't fit smaller sizes (i.e. 1-2 ounce). They fit both glass and plastic bottles in the sizes mentioned.So if ordering these it should be for bottles 4 ounce and above since these caps are too big for smaller bottles.Otherwise these are great to have to turn your bottle of essential oil into a reed diffuser. Gold is also pretty.
