A seriously satisfyingly king-sized piece from TitanMen's Master Tool collection, the Master #4 is extra durable, challenging enough for all you butt play pros, and proudly made in America. Shaped into a bubbly set of three graduated swells, the Master Tool 4 stretches and stimulates right off the bat.

In slick, glossy, body safe PVC, the surface of the Master Tool #4 gets super- slick with the addition of lube, both water and silicone based formulas will be compatible. Phthalate free.
