This penis pump from the Dr. Joel Kaplan collection features a classic and simple design with a see-through cylinder, soft, detachable donut, squeeze bulb pump, and a flexible hose. The suction is created using the easy manual squeeze bulb, and the vacuum can be released using the quick air release.

When the penis is inserted into the cylinder, the soft TPE donut at the base helps to create a vacuum-tight seal. Squeezing the bulb draws air out of the chamber, and the resulting suction causes blood to be drawn into the penis. When used correctly, this helps the user to temporarily achieve the maximum size and firmness of erection.
