Non-vibrating prostate massager built on a patented pivoting mechanism: pelvic-floor contractions rock it into hands-free rhythmic motion, engaging the perineum as it strokes. 5 inches overall, 4.25 insertable, 1.1-inch width, 3.6-inch girth. Rigid, weighty, body-safe, non-porous, and easy to clean. Stillness, made to anchor.
