A curvy, thrilling, satisfyingly sturdy edition of the Master Tool collection, the 
Trainer #4 is, like the rest of this man-loving line, extraordinarily 
durable, comfortably suitable for long term wear, and made proudly in 
America.
Shaped into a bubbly set of three gradually larger bumps, the deliciously stimulating widening and tapering  of the shaft  stems from a smooth, glossy, spherical head that's positioned to tickle the 
nerve-ending packed prostate perfectly once fully inserted. The 
Trainer edition is sized for novice level manageability- precision 
tapering, gradual widening and a nice slim neck combine to make the 4 
easy to insert, simple to maneuver, and comfortable for longer term 
wear, thanks to a nice flat base.
Made from a safe PVC with an 
all-over slick gloss, the surface of the Trainer gets fantastically 
slick with the addition of lube, both water and silicone based formulas 
will be compatible. Under the smooth, firm outer layer lies a core of 
Doc's signature Sil-A-Gel, this antibacterial jelly lends subtle 
flexibility to the texture of the Tool. Phthalate free.
