The pressure gauge will show your progress, but your penis will show it even more! This heavy-duty pumping set includes a 9 inch cylinder with measurements along its length to show your gains as you get longer and girthier. The extra wide base helps you create a tighter and more comfortable seal, made even easier with a little bit of lube. The ergonomic hand pump features a built-in pressure gauge, as well as a flexible and durable silicone hose. When you are satisfied with your engorgement, a quick release valve will instantly decrease the suction, freeing your ultra-sensitive penis for more hands-on play! Measurements: Cylinder is 9 inches in length, with a diameter opening of 1.8 inches. Hose is 12 inches in length. Material: ABS plastic, silicone Color: Black
