Featuring an ingenious design complete with PSI gauge and big trigger handle, this Pump is more than up to the challenge of maximizing your powers of satisfaction. Nice and steady at the sturdy calibrated (in inches and centimeters for you metric folks) cylinder, the Power Grip is comfortable in hand. A soft silicone donut sleeve around the mouth protects and cushions skin. It also works to ensure a super snug air tight seal. In body safe ABS plastic and silicone materials, the Power Grip cleans easily using warm soapy water or a good toy care fluid/foam. Compatible with any favorite water based lube. The Momentum Power Grip is approximately 9.5 inches insertable and 2.5 inches in diameter.
