The rigid core gives it a nice firmness while that sliding skin outer layer still feels soft and natural in the hand. At 21 cm it's got real length to it, so take your time with it.

The sliding skin layer honestly feels closer to the real thing than I expected, and the rigid core keeps it from bending awkwardly. Been using it a few times a week and it's holding up well.

I was worried 21 cm would be too much, but the firm core keeps it steady and the outer layer warms up fast against my skin. Honestly feels closer to the real thing than anything else I've tried.
