Press DOWN on where the sprayer cap was, using the syringe, and HOLD it down while you SLOWLY pull the syringe handle up. It might take a few tries but it does work. The secret is to PUSH DOWN on the sprayer cap (which opens up the tube to release fragrance. If the sprayer cap is pushed up, it won't extract). Test this out on less expensive perfumes. | ADAPTER FOR INJECCTION: Similar to extracting, you just need to replace the extraction tool with the injection tool, and slowly push down the syringe. When your at using the function to fill the bottle, if you notice it not going in just maneuver around slightly for better alighnment. This injection tool can let your high-quality brand perfume bottles be reused. No longer to regret that the perfume bottle can only be left idle or thrown away after using up the perfume. | EFFICIENT REFILL FROM NOW: Before our perfume refill transfer tool appeared, people could only use traditional tools to pump so many times to transfer perfume, and the efficiency was slow. But our tools can achieve the effect of rapid extraction of quantitative perfume and one-time transfer. Greatly saves the time of repeated filling perfume. | THE PERFECT KIT: Uses the syringe to dispense, combining two inventive adapters to extract original perfume from the original perfume bottle and inject the perfume into another original perfume bottle or other screw travel bottle.
