There is a specific kind of fullness that you control completely, and once you know what that feels like, you understand why this plug exists. It starts smaller than it finishes, and that gap between the two is entirely yours to manage. You decide how far you go, and you can stop, hold, and stay there as long as you want.Insertion is easy because the tapered tip gives you a natural starting point with the right amount of flex to move with your body instead of against it. Once it is in place, you attach the squeeze bulb and inflate gradually until the sensation is exactly where you want it. When you hit that point, the plug holds its size even after you detach the hose, so nothing is in the way and nothing changes unless you want it to. The quick-release button lets you deflate and remove it gently when you are done. The suction cup base means you can also mount it on a flat surface and use both hands for whatever else you have in mind. The silicone is phthalate free and body-safe throughout.This is a well-engineered toy from a brand that has been doing this a long time. If you want adjustable intensity and full control over your experience, this is the obvious choice.Overall Length: 6.25 inches (16 cm)Width: 1.75 inches (4.5 cm)Material: Body-safe silicone, ABS plasticPhthalate Free: YesBase: Suction cupWhat's Included: Silicone plug, squeeze bulb, detachable hose
