I wasn't sure feathers would actually feel like anything, but the green ones on this are genuinely soft and give this light, teasing drag across the skin. The other end adds a nice contrast when you want something a little firmer.
I wasn't expecting the dual-ended design to matter much, but switching between the feather side and the other end mid-play is half the fun. The green feathers drift lightly enough to make my partner shiver, which is exactly what I was after.
