This universal ribbed penis pump sleeve is exactly the same as the one supplied with the CalExotics Automatic Smart Pump - so you can order a new / replacement.
But it is also suitable for many other penis pumps with a diameter of ± 5.75 cm. You slide it into the penis pump and fold the outer edge around the outside of the pump. When pumping, the sleeve (and your penis) sucks itself in more. You will grow taller and at the same time enjoy sucking and ribbed stimulation.
Tell me honestly: Isn't that what every man wants?
