This is the small Sybian attachment and it is not compatible with the penis extensions. It comes with a spring fitted together with two white rods if you want a firmer internal action on your Sybian.

There is no latex in Sybian parts. All inserts are made of a material known as Dynaflex which is a TPE Compound and Kraton. No allergic reactions have ever been reported. The insert is beige flesh coloured.

Water based lube is recommended with these inserts.
