Conjure up a stupendously firm erection ready to go the distance with the magically effective (and glow in in the dark!) Classic from Shots' Glow In The Dark collection. 

A user friendly design makes for a great experience for beginner to master pumpers, simply slide on into the firm plastic cylinder and squeeze the simple ball valve to activate inner suction. Steady inner pressure draws blood to the penis while a soft silicone donut sleeve round the entrance cushions skin. That sleeve also helps create an airtight seal by the way, something you definitely want when pumping.

Graduated measurements run up the side of the cylinder in both inches and centimeters, you'll be able to easily track progress with those as well as visually- the cylinder is transparent. Assembling easily and quickly and coming apart just as fast for through cleaning, the Classic can be transported just about anywhere.

In firm plastic and soft silicone, the Classic cleans easily using warm soapy water or a good toy care fluid/foam. If you'll be using a lube, please pick a favorite water based version and pump away!  

* The Classic measures approximately 9.75"/24.8cm long and is 8"/20.3 penetrable. The inner diameter is about 2.1"/5.3cm, and there's lots of room to grow.
