the pin point tube is made of either aluminum or plastic, its collaboration partner helped to come up with the intelligent closure system. instead of being screwed on, the applicator is attached to the tube using a snaptype fixing. when the tube is squeezed, the silicone tip acts as a valve and allows the contents to flow out through a small opening. this is the secret behind the tip which ensures that the contents can be applied cleanly. the tip subsequently closes again. it cleanly interrupts the flow of the contents and also protects the substance in the tube against oxidation. in turn, a plastic cap on the pin point tube itself protects the silicone tip against environmental influences.
