• It fits tightly into the mouth of the bottle, allowing you to easily adjust the amount you want to put. • It prevents the liquid from dripping during casting. • Since its upper part is metal, it is resistant to breakage and falling. • The bottom part is made of black silicone material and allows you to insert the stopper tightly into the bottle. • If you spend a lot of time in the kitchen, you are probably tired of bottles with sticky exteriors. Thanks to this small device, your hands will stay clean - your kitchen floor will not be dirty with substances leaking from bottles. :)
