The Aroma Topper is an ABS plastic flip top that converts aroma bottles into a single-handed, open-and-close cap. It comes in two sizes, small and large, and fits most brands on the market. Prevent lubed up two-handed bottle opening and closing that leads to spills. Plus, no more searching for the cap! The top is easy to flip open and close with thumb and features a nose cone that makes it easy to fit to your nostril. There is also a click sound that indicates the cap is closed. Avoid spills, odours and stains with the Aroma Topper. Please be advised aromas have an extremely low viscosity and therefore easily leak or spill. The Aroma Topper is to assist during use. It is not intended as a longterm storage cap. Reattach original aroma lid between use. Also be advised tipping the aromas with lid open will not prevent spill. - Single Handed Aroma Use - Cone Shaped Inhaler - 2 Sizes - Easy-To-Use Flip Top
