The Aroma Topper is a flip-top cap made of ABS plastic that allows you to open and close aroma bottles with one hand. Available in small and large sizes, it fits most brands on the market. It eliminates the need for two-handed opening and closing, preventing spills, and you wont have to search for the cap anymore! The top can be easily flipped open and closed with your thumb and features a nose cone for easy fitting to your nostril. A click sound confirms that the cap is securely closed. The Aroma Topper helps avoid spills, odors, and stains. Please note that aromas have a very low viscosity and can leak or spill easily. The Aroma Topper is designed for use and not for long-term storage; reattach the original aroma lid when not in use. Tipping the bottles with the lid open will not prevent spills. - Single-Handed Aroma Use - Cone-Shaped Inhaler - 2 Sizes - Easy-To-Use Flip Top
