One of the first toys that I designed using CAD software, Knucklehead was initially 3D-printed in rigid ABS plastic, which I then cast into silicone.
The fat, blunt head pops in nicely, followed by a thick, expanding shaft. An intense hole-expanding dildo, Knucklehead's sleek design is ideal for guys who prefer the stretching sensation with a friction=free "in-and-out."

Dimensions are provided for your convenience to the best of my ability. However, as these items are hand-made, silicone is flexible, and measuring techniques vary, measurements are not to be considered exact.
