I'm currently using these with the 2 oz PET Boston round bottles for a personal, car and/or room spritzer. I cut the tube down to size for the bottle I'm using. It provides a great fine mist. In fact, I keep one filled with water and one of my favourite combinations of oils beside my computer and often reach for it.
