Ridges and ripples galore---this should have been a texture-lover's dream, but the shaft is a little too flexible to make me happy, and it bends at the narrow point six inches down the shaft. Still a wonderful choice for suction cup or harness use because of its long length and approachable girth, this texture should be great for those who want to dip their toes in, but might not satisfy those who want to "washboard" their inner passages.
