I think it is safe to say we have all spilled a bottle of Poppers in the throw! The Patent Pending Popper/Aroma Topper turns your popper bottle into a 1-handed, flip top. No more slippery, 2 handed battle with the bottle! In the past getting the bottle open takes 2 hands, keeping track of the removable cap is always a challenge and then actually screwing the cap back on, all while you have more important things to focus on! With the Popper/Aroma Topper just use your thumb to click it open and closed for a tight seal. Helps prevent spilling, staining and waste. The nose cone inserts into your nostril perfectly so you can get a huge whiff. The Popper/Aroma Topper fits most traditional popper bottles, but bottle sizes can vary, so the kit comes with both sizes, small and large, which will fit most bottles on the market. The Popper/Aroma Topper is the 3rd product in the Skwert line. For easy on the go clean, try the Skwert Water Bottle Enema. Also check out the Skwert Lube Injector that turns any lube bottle into your personal injector. Please be advised it is impossible for this product to work perfectly with every type of bottle that its manufactured. For storage and travel please seal in the cap provided with bottle. Do not store upside-down or on side with Topper attached.
